I think the greatest sin in the world is bringing children into the world that have disease from their parents, that have no chance to be a human being, practically. Delinquents, prisoners, all sorts of things just marked when they're born. That to me is the greatest sin — that people can — can commit.

Self-rejection is the biggest sin that you commit

The major sin is the sin of being born.

According to Aesthetic Realism, the greatest sin that a person can have is the desire for contempt. Because as soon as you have contempt, as soon as you don't want to see another person as having the fulness that you have, you can rob that person, hurt that person, kill that person.

The greatest sin, after the initial sin, is its publication.

The biggest sin in Satanism is not murder, nor is it kindness. It is stupidity.

Lying is the greatest of all sins.

Said the self-righteous preacher, "What, in your judgment, is the greatest sin in the world?" "That of the person who sees other human beings as sinners," said the Master.

I do not think idolatry the worst of sins. Cruelty is the worst of sins. It is far better to worship a false God, than to injure your neighbor—far better to bow before a monstrosity of stone, than to enslave your fellow-men.

The worst of sins are Infidelity (Kufr ) and Polytheism (shirk ) which constitute rebellion against Allah, The Creator. To eradicate these, Muslims are required to wage war until there exists none of it in the world, and the only religion is that of Allah.

There is no sin inherent in any mind save the sin of pride in believing one has seen or been taught the absolute truth. The second greatest sin is refusing to search for the truth one must acknowledge one will never absolutely find.

Ugliness is the greatest of all sins.

The real sin — perhaps it is a sin against the Holy Ghost for which there is no remission — is the sin of heresy, the sin of thinking for oneself. The saying has been heard before now, here in Spain, that to be a liberal — that is, a heretic — is worse than being an assassin, a thief, or an adulterer. The gravest sin is not to obey the Church, whose infallibility protects us from reason.

To remain silent and indifferent is the greatest sin of all.
