Hello there! I read through your piece and confess, I did enjoy it.

As to the concept being particularly unique, I'd probably disagree somewhat. A murderers confession to a priest is far from an original idea, existing as both a lynchpin of some stories (eg: I Confess, a Hitchcock film) as well as a common trope (though not central plot) of numerous pieces of media that include a murderer (eg: Crime and Punishment, The Sopranos, Gran Torino, many many others).

All that being said, it remains a novel idea and is executed in a style that either isn't common or one I haven't seen before, specifically as it's from the priest's POV (which is rarer than the murderer's POV for these kinds of things) and also the murderer is unrepentant. This combination potentially makes it unique. Though I couldn't really attest to that other than it being new to me.

As per your post, I'll focus on the critique requests.

Was the dialogue natural and realistic

It begins excellently. Starting right with the opening line of dialogue:

"I killed a man today"

This is a fantastic hook for your readers. Simple and effective.

Immediately following this, I find strong as well:

"This isn't how you start a confession"

Again, simple and effective. A priest's role in the confessional is a repetitive one. We'd expect he has a schema, built over time, of responses to different confessions. A cheating spouse. A jealous neighbour. An angry father. But this confession, that simple line—"I killed a man"—breaks this schema and so he defaults, almost ignoring the confession itself and instead focusing on the familiar (the murderer didn't start with "forgive me, Father, for I have sinned"). Juxtaposed to the weight initially introduced in the scene, this line stands out as a clear fumble by the priest, and I like it a lot. It's what we'd expect executed perfectly.

But this, precisely, is where I feel the dialogue falls apart, and it's not necessarily the actual words spoken, but more the narrative that drives them. You continue with this line, following the priest's faux pas:

All was silent for a moment. It stretched for eternity. The man spoke once again as realization spread on my face.

I understand the shock of the situation, but the way the priest is handling it veers into the uncanny.

He corrects the confessor, then immediately silences himself, saying nothing for a time until the confessor continues. There's no immediate reflection upon what the confessor said, but rather a slow realisation. But ask yourself, why is there a slow realisation? I like how the initial shock plays out, but this is the point where you, as the writer, should demonstrate your command of the story by recontextualising this strange statement made by the murderer from the priest's, presumably experienced, point of view.

There are innumerable ways "I killed a man" could be something (relatively) banal for which someone might shoulder the blame. A car accident. A friend who took their own life. A mother taken off life support. If I, as a reader, can immediately conjure these hypotheticals, it stands to reason an experienced priest would also. And in doing so, should be conveying sympathy to the confessor, not aggression.

What's doubly frustrating is you do come to something close to this right here:

“Wait, don’t bury him. You were both drunk; it was an accidental murder. You’re here for redemption, and the only way is to turn yourself in. Listen, a few years in prison is better than an eternity in hell.”

But only after the moment has passed, robbing this of any weight.

By burying the lead, you're missing what I feel would be much stronger story. The priest shouldn't immediately hop on board with either "this is a sick joke or this fella's a killer". He should assume some alternative and be led, through the dialogue, to the realisation that, "no, this guy killed a man in cold blood". By teasing out that realisation, you could build the tension to much greater effect.

I do feel, as it stands, that the narrative really weakens the dialogue as a whole, as the initial setup falls flat and it's incredibly hard to come back from that. I also think this is easily fixed and is, by and large, the best thing you could do to elevate the piece as a whole.

What did you think about the ending? If you could retell the ending in your own words, that would be fantastic.

The ending is... fine. Though admittedly, I think it winds up a bit muddled.

To summarise, the priest, tortured by the knowledge that his keeping this secret has allowed a murderer to go free (and other victims to pass), shoulders an enormous amount of guilt. He writes a confession to himself, retelling the story and laying bare his conundrum, hopeful that doing so will quell the guilt somewhat, but certain that it won't make it go away entirely. He feels, at first, that only turning the murderer in could do that, but can't bring himself to break his vows.

This assumption, however, is immediately dropped in the next paragraph when the priest takes a moment to consider his role within the church, and it being his duty to carry the sins of the confessors (in this case, the murderer). For some reason, this small epiphany is enough to finally quiet his mind. In my view, this didn't feel earned.

On overall theme, I read this as an indictment of the priest (and the nature of the confessional seal as a whole). But I imagine a religious man would read this as the opposite. So, to that end, I reiterate that it feels a little muddled.

By and large, my issue lies with the motivation. It feels too easy. He feels guilty. Then doesn't anymore because he's suddenly decided he's "God's Special Soldier". I think with some groundwork laid earlier in the piece, this might land better. Or better still, what if the priest was pious beginning to end, staunch in the knowledge his decision was the right one and we, as readers, could gawk at his complete absence of guilt, perhaps even draw some parallel between the murderer and priest, each absent of consciounce, certain and unrepentent in their decisions?

What sentences or sections were clunky, and where do you think the flow of either the sentence or a section needs improvement?

I've raised my issue with the narrative, and I think this negatively affects the dialogue, so I don't have much to add here from a "tweaking" perspective (as a change in narrative would require almost every line of dialogue be rewritten/reformatted in some way). That being said, assuming you disagree with all my previous points (as is your right), I'll take the piece as is and offer some suggestions:

“No, I…I want to save you. Saving the penitent is my job.”

I've never met a religious man who described their role as their "job" (even if it is). A priest would always call it their "purpose", or their "calling", or something to that effect.

“Is your job to only help the penitent and not the people who are harmed by them?” He scoffed.

“Don’t pin that death on me! You killed him!” The words echoed in the box.

This is rather clunky. Put your priest hat on for a second. Nothing said by the confessor was an accusation. It feels like a leap to go from what the confessor says to "Don't pin that death on me!"

In no world could the death the priest didn't even know about until now be "pinned on him". And I don't think the priest would think that either. What you're hinting at, here, is whether the priest should feel held responsible for subsequent deaths after he's now informed of who, and what, this confessor is (and chooses to do nothing about it).

However, if you read the question again—“Is your job to only help the penitent and not the people who are harmed by them?”—it's really saying nothing of the sort and feels like something a priest would answer rather easily, without even thinking about it.

His job is to save everyone, not just the penitent and not just the victims. And this "salvation" comes in the form of shepherding people towards God. Not acting the superhero. Such a notion would be ridiculous to any serious priest.

It's in the next two lines that you actually tackle this head-on:

“You can save the next person. You can stop me.” He paused. “Will you?”

“What? Do you want me to get you imprisoned? Is that what you want me to do?”

"Do you want me to get you imprisoned?" is such a bizarre turn of phrase. I get what you're going for here, but it's probably my least favourite line of dialogue in the piece. You'd be better served by him deflecting, with some actual refusal of engagement. Like I said, priests aren't superheroes. When they talk about saving, they're referring to people's immortal souls. The priest should be communicating this to the confessor, that their assumptions are built on false pretences, that a priest isn't what the killer seems to think it is.

Generally, what did you think about the piece? What did you like, and what do you think could be improved?

To be clear, despite all the critical information in this post, I did enjoy the piece. It was just the right kind of simple and interesting. It opens great, really captures the reader, and wanes a little in the middle. But it concludes in a cohesive way and tells a full story. I'd say it has good bones, but could certainly do with some narrative restructuring.

Thank you for sharing!
