Each time Batman beat, did not kill, and captured the Joker for arrest the judicial system ruled him insane and he was held in a high security psychiatric ward/prison vs killing him. So, using the same measure, you could blame the laws, judges, juries, doctors, etc for all of Jokers future crimes when he broke out agian.

If you want to disarm this guy all you have to do is take his pencil.
