I believe we are looking at it from different directions. You say people want to enact revenge on bad people, sometimes violently. I say people want to be violent and hope for someone bad to appear, so can do it without moral repercussions.

You are probably right. And nazi zombies even more so.

I believe many people carry with them a deeply buried desire to hurt people, but their morals keep them from doing it to just anyone. But they yearn for a chance to do it without moral repercussions.

Is it true, that the colour flakes off?

What do you think of my business idea of dogtoys that smell like illegal stuff, so you can train your dog to sniff out things. You have a ball and it smells like cocaine (there is no cocain in there), but you can hide it and train your dog now to sniff out cocaine, just for the fun of it. And there is one, that smells like explosives, one for marijuana, one for meth and so on.
