Errors do not a bad parent make.

Predictable errors do.

Or, to put it another way, suppose you woke up in the Christian Hell; would you plead that you had made the best decision on the available information?

Hell yes.

You cannot make me reconsider a probability assignment by pointing out the bad consequences if my assessment is wrong; you can only do so by adding information.

One way of assessing probabilities is to ask how indignant we have a right to be if reality contradicts us. I would be really indignant if contradicted by reality about Christianity being correct. How indignant would you be if Reality comes back and says, "Sorry, cryonics worked"? My understanding is that dogs have been cooled to the point of cessation of brain activity and revived with no detected loss of memory, though I'd have to look up the reference... if that will actually convince you to sign up for cryonics; otherwise, please state your true rejection.
