So I am in no way a gamzee apologist, I think he's literally the worst person in the comic, next to maybe caliborn, but how would you compare him to vriska, who's also a murderer and was in an abusive relationship (cause vrisktav is not healthy.)
Pretty close on the douche-o-meter.
Gamzee being just a bit farther along because he doesn’t even kinda-not-really-but-sorta feel bad about stuff he does like Vriska and because he’s an antagonist.
