Out of curiosity, are you the type that, if you played this game, you would have to go out and torture small animals? I can't imagine where else you would have gotten the idea.
Actually no, I don't believe a person's personality can be altered by a game, but I do (to an extent) believe that a person's choice in games can be a reflection of their personality.
Of course it's not always the case, I know people of "sound mind" may find this game entertaining, but I can't help but think this game will be a magnet to very disturbed people.
