The problem is the chance of being revived into a life worse than death. If a life of torture is preferable to you than dying this is a risk you don't really care about, but if you're worried about it you should take it into account.
Sure, take it into account but take into account the probability of that as well. I tend to look on the dark side of things, but have recently taken to heart that the probability of The Bad Thing is usually quite low.
Maybe some crazy people will snatch me up in the night and torture me too, but I'm not going to lose sleep over the possibility because of it's low probability.
In considering the pros and cons of cryonics, has anyone addressed the possibility of being revived in an unpleasant future, for instance as a "torture the infidel" exhibit in a theme park of a theocratic state? I had some thoughts on the issue but figured I would see what else has been written previously.
