True, people in such times were treated much more harshly by the law... but for the most part, they led relatively untorturous lives. I say relatively in comparison to Hell. They may have had to work for little gain, but the brave majority did it all their lives and it's something that they thought must be done, and that had a purpose - their own survival. Hell is just punishment without rhyme or reason, or even much judicial control. And being flayed alive wasn't something typical to the normal peasant, either. Perhaps more common than nowadays, but it still wouldn't have been every other person you meet - not by a long shot.
I have an insight in regard to the "problem of hell" that may be salient. Basically, how severe of a punishment something is can be seen as how much worse it makes a person's condition, so while being flayed alive in a pit of lava may be severe to us living in 21st century free countries it would be a comparatively much more mild worsening of conditions to someone living in ancient squalor under mosaic law.
In the bible, the actual punishment of hell is spending an eternity without God. You would go through the judgement, so you would witness God's full glory, then be sentenced to a life without him forever.
The Bible seems to put it much more physically.
“Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels."
Any Biblical passages saying Hell is only separation from God?
Edit: And then a webpage gave me these...
