In order for you to be revived in a hellish world, the people who brought you back have to be actively malicious, which doesn't seem very likely to me.

They might also be high-functioning but insane, from some of the very many ways tech at the level of mucking around with physical human brains to the degree of successfully reanimating cryonics patients can go wrong. With the original imperative to revive cryonics patients intact, the ability to do so also somehow intact, but things being very, very wrong otherwise.

I think "you might wake up in hell" is actually one of the better arguments for opting out of cryonics, since some of the sort of tech you need to revive cryonics patients is also tech you could use to build unescapeable virtual hells.
