I'm afraid I can't accept this. One of the requirements for creating a character is that their personality be the same as their base character. Bruce Wayne isn't the kind of person to want to watch the world burn. However he is fueled, in part, by revenge, if you could find a way to use that to make him a villain then I think I can accept it.

But you said the world was altered so couldn't in this altered world rather then lossing his parents. everyone lived. He just wants to rule the world or watch it burn due to the fact he sees humanity as a plague. He will do what is necessary to stop the plague and reforge a better man or destroy it.
