How do you usually like to play your game characters when there is a choice of "good" and "evil" decision in the game?

As much as I love many of the villains in video games, I find that when I personally have to make a choice between a good action or a more villainous one, I go for the good action. Even though it's just a video game, and my decisions won't effect anyone else other than the characters in that game, I still feel better following the path of good. I guess I like to play the part of the hero or something.
