To protect the overall organization and potentially to protect other people in his life. My impression from looking at the documents is that this is a very large international network. I imagine there would be consequences for being caught, such as the torture and murder of everyone you hold dear. If your only options are to kill yourself or to get murdered and have everyone around you also tortured and killed, I could see a narcissist choosing the former option.
I don’t know anything for sure, but the released files definitely gave me the impression that Epstein was not the top of the chain. Rather, he seems like the American representative of an extensive global cabal. Somebody out there was putting together those sample albums of girls for him. Somebody was running the brothels he seemed to be visiting. He was getting calls from all over the globe with descriptions of new girls. It seems to go much deeper than just Ghislaine trolling the local middle schools for fresh meat.
So, if he did kill himself (heavy on the if), then I’d imagine it was partially because there is a scarier monster out there who is ready to take out the trash if anybody gets sloppy.
You misunderstand me—I can see them being ok with torturing family members, but if the options are to either die by suicide or die by murder plus they demolish your empire, I think there’s a chance that they choose the former.
