I just wish people would stop and really think about the consequences of their actions. Not only has this person injured (almost killed) and scarred a poor defenceless cat, they have caused a huge amount of distress to other people too, the owner of the cat, vets, police, neighbours who were out searching for the cat etc.
I wish they would, just even for a second ask themselves the question "If somebody did the same to me, how would it make me feel?". And then for them to empathise and understand what their behaviour can do to others. It's so sad that we live in a world like this
