Just want to give an example of the principle of the best way to deal with this, as Rad answered.
I was deeply struck when I first saw this, years ago in the movie Gandhi. More and more I understand why. It is such an example of this principle.
During that fast, toward the end of the Gandhi movie, a devout Hindu came to Gandhi and said, “I am going to hell.” Gandhi asked, “Why?” He said he had killed a Muslim boy during the violence that sprang up as the country was being divided into India and Pakistan. Gandhi replied, “I know a way out of hell. Find a child whose parents were killed in the violence and raise it. Only make sure it is a Muslim child and raise it as a Muslim.”
Think of the implications of a devout Hindu raising a child as a Muslim, and the effect that would have on the Hindu man's natural guilt, and also the effect on the child's Soul, whose parents had been murdered by Hindus.
