It needs to be noted that we never undergo punishment or torment in the next life on account of evil we have inherited, only on account of evil that we ourselves have actually committed.
When the evil are being punished, angels are always present, tempering the punishment and easing the anguish of the wretched. They cannot eliminate the pain, though, because everything in the other world is balanced in such a way that evil punishes itself. Unless wickedness was removed from wicked people by punishment, they would have to be kept in some hell forever. Otherwise they would infest communities of good people and inflict violence on the system of order established by the Lord, which ensures the welfare of the universe.
