I.e. if we simply could abandon that at the flip of a switch, I'm not sure if we should, it's plausible that it would make all kinds of abuse less risky and thus more attractive, increasing the abuse happening in the world.
Wolves normally don't do that. Not unless they have rabies. We should stop seeing the nature as if we were still in the XVII century.
The logical answer would be to direct the revenge against the real culprit, the rabies virus. Kill the rabid wolf and vaccinate other local wolves against rabies. Wolves learn quickly that must keep their distance with humans. Culling all the wolves in the area leads to more humans killed, by herbivores.
Animal control tries to do just that, control. If a written sign would be enough, those wolves would not have been culled (except maybe the ones which actually killed tje child).
Not being slaves to our animals instincts is kind of what makes humans human.
Unfortunately while this behavior is useful at conquering the world, it becomes counterproductive later on.

Otherwise you get into a cycle of revenge for revenge for revenge that wastes everybody's energy.
