If your brother was a supervillian (no, mine isn't. What's he going to do, goofball you to death???) How would to introduce him at parties? Would you want the noteriety of having a supervillian for a brother, or would you use his regular identity and pray he didn't decide to take over the world while you nibbled appetizers and drank booze? wouldn't you be terribly embarassed if a superhero came flying into your party for an all out fight? would you cheer for the supervillian or your brother? I mean, he is yor brother and you are supposed to love and support your family, right?
I guess you can look at it this way, in a more serious note, and I would love to hear some feedback on this, if you knew your family member had killed someone, would you turn them in??
And now, back to my regularly scheduled cinnimon roll.
