I have a hard time believing you respect human life if you're defending someone who would take yours (perhaps not intentionally) in a heartbeat.
First of all, I'm not "defending" anyone. The kid was wrong to throw the eggs. However, he didn't deserve to be murdered because of it.
You, however, are defending someone who deliberately took a human life in cold blood, motivated by nothing more than a desire for revenge. That shows how little YOU respect human life.
