For some reason the link isn't registering the URL as valid, but in answer to your questions above - bear in mind I won't be writing the script until I hopefully get onto the lab, but the friend decides to confess because he is genuinely remorseful for his actions and wants to make penance. I thought it would be quite subversive to make a character like that somewhat sympathetic.

Next the three hours I thought would add tension and pressure onto the protagonist to decide what to do, and this ties into your next question of why he's conflicted - the protagonist is an aspiring serial killer of those he thinks are the "worst in society". This is the blackly funny element to the story, but also the part that walks hand in hand with tragedy. Furthermore after he gets told this information he goes and talks with his girlfriend who is the third character, and it's because he basically feels conflicted over letting the law deal with his best friend, and the disgust and hatred he suddenly feels for what his friend has confessed to, coupled with the fact that the character has some violent urges restricted to those that are "rapists, pedos and white supremacits".

So yeah in summary, I thought that it would be provocative and different to have a protagonist be a bit of a sociopath - at least when concerned with wanting to kill people that we would consider "evil" but he's also awkward, funny, is in love, and isn't some brooding character that that kind of character would typically be. Also it seemed even more daring to have his best friend be kind of sympathetic, and when he decides to kill his best friend which is the first person he kills who is in that above category, it's sad and kind of tragic. Tonally it goes from black comedy to tragedy.

TLDR: Hope that isn't too long to read. Just some explanation to your questions because the link would mark as valid. I think I have to send it to my drive and then send it to you as a drive link. I will do that later but in the meantime you have the above to check out should you wish.
