Kitten clubbed to dealth

I can't imagine how I would feel of something like this happened to my cats one of whom is sitting beside me as I write this post.What was going through those young peoples minds when they killed a defenseless kitten right in front of it's house while children watched.The poor girl that owned it must be devastated,it's hard enough to lose a pet any time but especially in such a cruel and unnecessary manner.The kitten must have suffered terrible pain in it's last minutes.
