Why did Dally break the laws in the book The Outsiders?

Becasue he comes from a bad home so he is just a bad kid.

AnswerNot only because he comes from a bad home but mostly because he got put in jail once and it made him hard as a rock in his heart, he realized his parents didn't care about him and that the only people that do are his gang, the "greasers", and he feels that if he is in jail, that when he gets out, all his problems will go away. He just didn't care anymore.
