Anything’s possible, friend.
How can a mother strap her kids into the family Toyota, and drive it into a lake?
How can another young mother drown her children in the bathtub, one by one?
There only explanation is “Sh*t happens” because evil exists in the minds and hearts of people.
Maybe if we weren’t busy creating victims someone might have tackled the kid and ended it a lot sooner.
When I was in school back in the 80s some idiot tried stabbing a girl in the hallway. In the space of about 3 seconds he slashed her arm and raised the knife over his head to stab her and had a half dozen students on top of him on the ground.
