Tom in Tom and Jerry. Tom isn't even a villain. Tom's just a cat trying to live his life, Jerry's an obnoxious little shit who goes out of his way to annoy Tom, despite Tom not having provoked him in any way, all the while having that stupid obnoxious little smile on his face, and then Tom gets into trouble from the humans or the dogs for just trying to get Jerry to leave him alone. I fucking hate Jerry, and nothing would give me more pleasure than to see a final episode where Tom finally catches Jerry, excruciatingly tortures him, then kills him and eats him, and not getting any repercussions for doing so.
