I'm still contemplating if I should lie to myself and say "I can totally do an asshole playthrough this time!" only to end up doing the exact same things as I did last time because I can't stand making lines of code sad.
Dark Urge made it easy for me. I kept wanting to do an "evil game" but would always lose heart and pick the nicer choices.
And then my group made me the Dark Urge character on a different playthrough. And once I realized some of the evil shit was beyond my control, I just kinda said "Fuck it" and went evil as possible.
