Yes, and then if you retaliate you're in exactly the same situation as the moron that either hacked or had it caused to be hacked. What is disturbing, from eight million miles away, is what seems to be a strip of bark attached to the top section of the tree. That means that there's a corresponding bare patch on the stump that should have been immediately closed, with tar, even paint, to keep infection out and to prevent sap loss, if it's flowing.
This is what angers me about forums. So much energy displaced through the keyboards, so much endless discussion, and the trees lying there, in pain, unattended. Obviously I am anthropomorphising, but the point is there. And why do people just feed the birds in the summer?
