Bill Cosby
This one differs from the others on this list because it’s not one of these “Wow, did you know this largely unknown but concerning fact about this person?” circumstances. I mean, isn’t everyone aware of what Bill Cosby did and why it’s so awful?

But I think he really resonates with the main theme of celebrities who have disappointed you. Because as this poster pointed out, Bill Cosby let all of us down in an authentic way. He always seemed like this respectable guy who wanted us to be our best selves–like that one teacher you had in high school who expected a lot from you but also brought out the best in you. So it was an even worse betrayal when we found out he’d done some terrible stuff.
