You should teach others with a good example, but if you teach with evil, then you do not teach, but destroy.
Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
— Matthew 18:21 22
Sinful people had once accepted their right to punish others and most of our misfortunes started from this.
If you think someone is guilty of wrong doing you, forgive him. If you have never forgiven the guilty before, you will experience a new joy: the joy of forgiving.
Punishment is always cruel, always painful.
The American Indians had no laws, no punishments, and no government. They obeyed the moral understanding of good and evil that is part of every human nature.
— Thomas Jefferson
The strongest proof that in the name of "science" we pursue unworthy and sometimes even harmful things is the existence of a science of punishment, which in itself is one of the most ignorant and offensive types of action known to man, a vestige of the lowest level of human development, lower than that of a child or a madman.
