Most Christians, Jews and Muslims believe that when we die we will come to stand before the throne of God and have to answer for our lives and whether we believed in Him or not.
Hell is not clearly defined anywhere in either the Jewish or the Christian texts, but only mentioned as a concept, and I believe much the same exists in Islam . We are told that the unrighteous will not be admited to the presence of God, but not what else, if indeed anything, will happen to them.
Standard Jewish practice has wisely refraned from attempting to picture the after life, whether people have been good or bad.
Most modern Christians have come to see too, that we cannot know anything about what it will be like, as the Gospels do not tell us that. Christ said to the dying robber "This day you will be with me in Paradise" but said nothing about what that would be like.
Modern thought amongst Jesuits holds that if we are able to answer truthfully that we believe in God at the moment of our death that may be all that is required of us.
This fits in nicely with the concept of a merciful, loving God, but may well seem unfair to anyone who has suffered at the hands of an evil person.
Belief in an almighty and omnipotent God must surely lead us to realise that only God can know why any one of us do or did the things we did and whether the evil that anyone did was in the words of the Bible "necessary that good may come of it" - a hard saying that I certainly do not pretend to understand.
Try to do as much good and as little harm as possible in this life and leave the consequences of it and the afterlife to God.
