It is both stupid and short sighted, but I can't help but feel for the people on the other side too. The difference is, however, their wounds will be more likely to heal (if they allow them to) than this man's, and sorry if these folks can't cope with losing loved ones, but they have a greater chance of thriving on their own without help.
Besides, murdering someone else isn't going to help them get over their loss and trauma in any meaningful way.
