Epstein showed a lot of interest in all kinds of scientifically and ethically dubious ideas like eugenics, and he actively prodded people in favor of these ideas at the dinners, parties, and jet rides he hosted.

This was not a case of a guy just writing a check and receding back into the woodwork. (Even if it was, I'd still say "trafficking children to be raped" is a bridge too far on the path of "ethical violations which are sufficient to refuse donations.")
