Lily talks to zach about his anger

when Zach admitted that he was angry with racism and Lily told him that she wanted him to work on not being angry so that he doesn't end up being a bully. I don't think that Zach would ever bully I just think that he would defend himself because of last incident with his friends. his character is to good that I don't think he would bully out of anger. do you guys think that he would bully?
