Actually, Gunn's old gang would be more my style.
I'd like to think I'd distance myself from it once they took to "exterminating all demons," but in all honesty, if I'd been fighting even demons for years, I'd be exhausted and finding it futile, so a charismatic leader could--in those circumstances (placing myself in that sitch rather than seeing it from my own personal perspective)--have convinced me that a good defense was a good offense (even "kill them all, let God figure them out"), with a hope that one day the monsters would be gone. Of course all that fighting would've dehumanized me, or more precisely, dehumanized all demonkind, even the good demons unless I had good experiences with them as well. I think what they did in Caritas was reprehensible (and makes me think of the warning about not letting yourself become a monster yourself when you go out to fight monsters), but thinking of it from their perspective, it makes sense that it would be easy for them to sink that low while fighting the good fight.
