Did this bully get what he deserved?

That kid deserved it.  He started it, who cares if he get seriously injured...if the mouse picks on the lion and annoys him, of course the lion is gonna squish him to death.

You do something stupid to someone and, chances are, something stupid will be done to you. Yes, I think he got what he deserved. And, hopefully, this response prevents his bullying from escalating as he grows up. My concern, though, is for the kid that did it. If he'd seriously injured that punk, he'd have to live with that for the rest of his life - and, possibly be in trouble with the law. I found it interesting how that older teen (the girl in the background) didn't step in until the end. She also knew that twerp had to be taken down.

Well, that's people for you.  For most of us, watching someone get bullied is the most excitement we get in a day, so we enjoy it while we can.

The kid who started the altercation has just experienced a valuable physics demonstration about mass, and if he has an ounce of intelligence, he will learn from it.
