Well yeah, it was an extreme case I was referring to. Kids will be kids, but in the case of this story, they went way too far. Although I do not condone what the teacher did, he obviously snapped after years of putting up with this. It's not an exclusive case. People have thresholds. I don't think he pre-planned it. That's why we have murder and manslaughter.
