Like everyone else, I’ve been trying to answer the big question: why.
The only thing I came up with is this.
If you’ve spent your whole life being anxious and uncomfortable, feeling not in control, when the moment of breaking comes, making everyone else anxious and fearful and at risk makes you suddenly solid and in control of everything.
So much of what seems like anger and rudeness I see on a daily basis is really fear and feeling not in control. I try to tell younger folks this. It’s hard to show empathy when you feel attacked, contradicted, challenged etc.
Maybe that’s why these murderers commit suicide after causing such pain and destruction: they achieve at last that moment where they seem to be in control and there’s nothing that can happen afterwards that will be as good as that.
