On a more serious note: Just block the kid. If you seriously can't stand the kid, just block him rather than trying to attack him when he's minding his own business. And if you can't block him because "it isn't enough and you want him dead," then you have been diagnosed with Skill Issue, because that just means you're picking on one specific person as if he were a public punching bag.
Like I said, grow up and learn some human decency.
