He wasn't running a brothel and the vast majority of the people who had any contact with him did nothing wrong and were probably totally unaware he was a sicko. He didn't need money, so it's not like this was a business. All the blackmail talk and film of it is just rumors at this point.
He basically was a sicko who kept teenaged girls around for sex. And he kept them around for some of his friends or associates like Trump and Alan Dershowitz. Not defending him at all, but pedophile isn't even the proper term in this case, Ephebophilia is, these weren't children, they were girls aged 14-19 he was taking advantage of. It's wrong, it's criminal, and it's sick, but it's a totally different crime than if he was doing this to 8 year old kids.
The idea all of the thousands of people who he had phone numbers for were involved is silly, ditto to the hundreds of people who flew on his plane. He gave Bill Clinton the use of his plane to do charity work, this wasn't some leisure flight for partying. Now there are credible accusations against some of his guests like Trump, Dershowitz, and Prince Andrew, those are different. Those are real accusations of rape and abuse, not vague references to some of the victims saying they saw Bill Clinton at a party.
The whole thing has taken on a life of its own across the internet, like it was some massive organization for depraved sex and thousands of rich and famous people are involved. Epstein was doing all this stuff in private, I'd bet you the vast majority of the people who knew him were shocked when the crimes came out.
