There are people who have done wrong because they could not see the result of the wrong .... Evil begets evil. It grows. It transmutes, so that sometimes you cannot see that the evil in the world began as the evil in your home ... like a fisherman casting a net into the water. He keeps only the one or two fish that he needs to feed himself and puts the rest in the water thinking that their lives will go back to normal. No one forgets that they were once captive, even if they are now free.
