The embarrassed missionary apologized. Things like this happen. My dad was a practicing doctor, and he took it in stride. Petersen's gaming career fits in with his Mormon's life view. I don't think that a game can be evil any more than a car, a knife or a dollar can be.
Evil is something that is in the hearts of humans.
And unlike a car, a knife or a dollar, a game can't be used to hurt another person. Its only function is to provide entertainment, to blow off steam, to provide harmless amusement. Petersen does have a couple of off-limits items. He won't work on pornographic games, or ones in which a player is benefitted by killing harmless bystanders. The former Utahn likes to play PC games himself, and so do his teenagers.
