I heard a story similar to this where 2 men went to a village to work. On the way back from work they stopped overnight. One of the men got greedy and deicided to kill the other man and take his money he had worked for.
Years later the man got married and had a boy. The boy was constantly ill and couldn't get better. The man spent money on medicine etc to make his son better but to no use. When his son was lying on his bed ill, the man said to him that he's spent so much money on him but he isn't getting better. The son asked how much have you spent, to which his dad replied the amount. The son then replied thats how much you took from me after you killed me and now you have repaid it, and passed away.
