Do bullies ever deserve to be bullied back? (See inside)

I saw this video the other day, and was wondering whether or not you felt like the bully in this situation deserved what he got.

I for one would say he had it coming, but I maybe a little biased. I was bullied when I was a bit younger, not to an extent like this though. What do you all think? People say that there are nonviolent actions you can take to prevent and end bullying, but when see situations like this, I dunno how true it proves. Though I hope there will ultimately be a nonviolent solution, I’m not promoting children beating the snot out of each other.
