If you hate pedophiles so much you're willing to risk your life/career just to let one of them commit suicide, surely you also hate them enough to wait just a little bit longer to prevent a bunch more of them from getting away with it.
Why do you think that sleeping through overtime would be a case of the guards risking their life? I doubt they've even been fired.

Especially in this situation. We have huge motive, excellent opportunity and unless one of the guards is so stupid as to talk, almost no possibility of detection. A perfect crime, if there's one. Of course, there's no proof of that - maybe Epstein indeed was suicidal. Maybe the guards were just paid to give him an opportunity, not avoid witnessing murder. Who knows. But I don't see how guards sleeping excludes any of that.
Second, people are generally pretty bad at suicide, and the methods most likely to succeed (firearms, drugs, falling) are not available as options.
And IF people thought he had dirt on people then I would assume he would at least have a basic dead mans switch that would send out the dirt to the press in case of death; to prevent assassinations. Especially if there was an earlier attempt.
Also, from Epsteins perspective, actually having a dead man switch versus just letting people assume he has one has exactly the same impact.
So why bother setting one up? If the switch goes off, he will be dead, perhaps there will be retaliation against relatives. How would he benefit?
