I suspect that’s exactly why he became famous. He feels like someone you should hate, affable at first but there’s just something off, so you watch for it and his characters eventually display it.

I wonder if allegations against him were dismissed simply because he played that kind of character, and people assumed it was a character and not Spacy himself being the character he’s best at playing.

Or perhaps the characters he played eventually bled into the actor and he became that kind of person. That also seems to happen to actors over time.
