What leads Ender to violence?

The thing that leads ender to violence are the situations that he is "thrown" into that he has no control over. In other Words, ender has no control over the situations that happen around him, thus leading him to violence. For example, when ender first arrives in the shuttle with the other launchies, he is poked and shoved and punched. Before the next person can punch him, he trusts forward unaware of what he is about to do and breaks the launchies arm. He does not know why he did what he did, but feels terrible about it afterwards. Thats what leads ender to violence, hope this helps you out. I actually am answering this question when Im suppost to hand this in myself, so really hope this helps you!
