Robert Maxwell has been accused of being a Mossad agent. Ghislaine Maxwell was the daughter of Robert Maxwell. Upon his death, six serving and former heads of Israeli intelligence services attended his funeral in Israel, while Israeli Prime Minister Yitzhak Shamir eulogized him and stated: “He has done more for Israel than can today be said." https://en.wikipedia.org/wiki/Robert_Maxwell

I think some intelligence agency (even money CIA or Mossad) was using Epstein's tapes of powerful people engaged in pedophilia as kompromat to blackmail powerful men into being subservient to their interests.

Maybe not. From this article, "...it probably wasn’t American intelligence, either."

Why would a CIA agent do blackmail against American and western targets? That's not how it works.

If Epstein was killed, it's quite possible he was killed by US counter intelligence.

Honestly this seems the only reasonable explanation considering how long it was known he was doing what he was doing.
