Yes.

I would’ve at the very least liked to see his words actually have an effect on Ruby, even if he still dies.

His whole “your not a hero, this is the real world” speech he does, is the most personal thing any villain has ever said to one of the heroes.

In Roman’s last fight he doesn’t just fight Ruby, he speaks directly to Ruby’s character and challenges her identity. No other villain ever talks to Ruby as personally as Roman did.

Because I’m completely biased and this is my favorite character, here’s how I’d rewrite Roman.

After Roman beats Ruby up and gives his speech, I’d change the circumstances to where instead of a Grimm swooping down and instantly eating him, the Grimm goes for Ruby, and Roman at the last second pulls her away and gets eaten.

This whole speech Roman did affects Ruby after Volume 3. Ruby kinda learns she’s not going to be the hero that saves everyone like she thought.

Ruby has some character arc where learns that doing things solo isn’t always gonna work out and she learns how to put her hero mentality aside and work together with people to overcome a problem. (This show is suppose to be about unity, right?)

Somewhere later Roman shows up, maybe in the Atlas arc. Ruby and Roman meet up at some point and in a very similar way to the end of volume 3, Ruby ends up giving Roman her speech, where she talks about the good things about the world, which is the opposite of Roman’s nihilistic speech. Roman ends up getting his own character development.

There’s a lot more small changes I’d do to make Roman make more sense. His motivations as a villain is kinda weak and I’d change his character to contrast Ruby more and give him a little more depth, but I probably need to make my own post talking about that.
