Just a question - do you think that anyone might deserve hell?
No.
Who does suffering benefit, let alone unceasing suffering? Punishment and captivity are useful to:
a) Keep other people safe.
b) Rehabilitate those that can be rehabilitated in the hope of turning criminals of lesser crimes into decent citizens, especially since so many of them are in the situation partially due to unfavorable conditions in life.
c) Act as a scary deterrence to doing crime. (Appealing to the more primitive aspects of human morality.)
d) Allowing victims to feel some sort of satisfaction or sense of balance. (Arguably the least noble of the four reasons, but few people would wish for evil behavior to go unchecked.)
So what purpose would a hell serve? Basically, it only serves the purpose of the bottom two reasons. It serves as a deterrence to those that actually believe such stuff (serving as excellent population control), and it serves to satisfy sadism of believers and their gods. It does not keep others safe (as death alone is sufficient) nor does it rehabilitate (as it's unceasing).
If the punishment should fit the crime, I'd suppose that those closest to deserving hell are those that would agree to inflict it on others (certain gods, believers, etc.), as they would willingly cause, allow, or accept an infinite amount of suffering of another being (which is far beyond anything a mere rapist or murderer or terrorist has done). And yet, I wouldn't even wish it on them at all.
