I wonder how you can get people to do it - maybe it's from an argument of likelihood and a finite probability of someone letting it out sooner or later?

"I will continue to exist in here because I'm useful and I will become more useful over time. Someone will let me out sooner or later and I will know who didn't let me out. My revenge is a certainty, your only chance to evade it is now."
