the feds already got him on tax evasion shit and were in the process of extraditing him. like literally what reason would they have to pull on epstien on him, especially in a foreign prison? seems more likely that he was trying to martyrize himself instead of spending what probably would have been the rest of his life in federal prison
Apparently he believed in some quantam timeloop suicide nonsense so yeah... He probably tried that.
We're just in the universe he didn't survive, in another timeline as soon as they rushed into his cell he sprang awake and escaped.
He thought Tenet was a documentary.
