THat is why we learn from our past mistakes. We know some things are good and some are bad. We go forward to learn ; those who wish to learn. The most evil person thinks he is good in some way. Hitler thought he was doing the right thing.
Some of us think we are right but later on we learn that we were wrong. We keep on evolving . WHo are we to judge what the right method is. Many paths lie to
healing ,some go this way and some that way. We after all are learning good things
as well as bad things.
