Yeah I've told myself that a few times. My problem is I'm too nice of a person and have a really hard time being mean/evil, even to made up 1s and 0s. I've been in the military and know violence, hate, and anger, but I still have a hard time doing it to another "person", real or made up. I know I'm probably crazy but I like to think I'm ok with it.You should play the hate route up until the dinner, you don't need to go beyond. They shout a lot of things at each other while tearing each others clothes.
I think both routes ascribe blame to both, but MC does shoulder most of the blame as he took the extra steps to sleep with another woman.
Maybe I'll just suck it up and try it.
