If they wanted to make a point, why would they have Trevor do that?
What's with bad writers and thinking a point is made stronger because a terrible person says it? People won't think
>Wow, even the MONSTER won't sink THAT LOW!
they think
>That crazy bastard is acting weirdly eloquent this scene, no way in hell he talks like that here
or something like that. You'd think Michael would be the one to say that shit, or Franklin would be the one who would get the most fucked up by that experience and realize just how bad things are here. But no, they have Trevor do it, the unironic crazy bastard, just to make the whole "even the monster isn't as evil as this!!" point.
