I'm too young to remember Jackomania. In my politically moderate (by US standards) upbringing, he was the subject of many deeply racist, transphobic jokes, all juxtaposed with the child molestation thing. I dont really have any other memory of him, aside from the simpsons episode of him (made at the height of Jackomaia).

That all being said, any expectations I have were set by Talking Simpsons, and the fact that that is the only episode not on Disney+. The episode was very much made at Jackson's insistence. He had an unhealthy obsession with Bart Simpson, and the episode itself was made with his intention to lure more boys in. It was very much selling the fantasy of being plucked from obscurity by Jackson-as-sexless-music-elf, and you, a little boy, could stay up all night writing the next pop hit. A few of his victims even cited the episode, and one detail that stuck with me was that Jackson would invite boys over with their sisters, as cover.

Jackson had a deeply traumatic upbringing in the public eye, and I cant imagine the fame or racism went down easy, especially when that venom was all he knew. But there is no doubt in my mind that he did molest little boys.
