I stick with the good path, because I find it to be generally harder to do and you reap less rewards, but is far more satisfying then following the evil path.
I've tried to play the game as good, then redo it as evil, but when I start the evil path I feel compelled not to continue because of how wrong it feels lol.
Guess the long and the short of it, is that I just can't play evil cause it doesn't feel right
