Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Hate destroys a man's sense of values and his objectivity. It causes him to describe the beautiful as ugly and the ugly as beautiful, and to confuse the true with the false and the false with the true.

Hatred is the vice of narrow souls; they feed it with all their littleness, and make it the pretext of base tyrannies.

Holding anger is a poison. It eats you from inside. We think that hating is a weapon that attacks the person who harmed us. But hatred is a curved blade. And the harm we do, we do to ourselves.

[P]ride has no intrinsic substance, being no more than the name given to the soul devouring itself. When that loathsome perversion of love has borne its fruit, it has another, more meaningful and weightier name. We call it hatred.

Learn this from me. Holding anger is a poison. It eats you from inside. We think that hating is a weapon that attacks the person who harmed us. But hatred is a curved blade. And the harm we do, we do to ourselves.

Envy, bitter envy, was permeating his soul drop by drop, like a poison that tainted all his pleasures and made his life hateful.

Despite all the positive psychological attributes of hatred we have outlined, hatred destroys finally the core of the life of the hater. While it lasts, burning in white heat, its effect seems positive and dynamic. But at last it turns to ash, for it guarantees a final isolation from one’s fellows. It blinds the individual to all values of worth, even as they apply to himself and to his fellows. Hatred bears deadly and bitter fruit. It is blind and nondiscriminating.

Hatred is a feeling which leads to the extinction of values.

It may be that hope misleads. But hate—hate corrupts. I have been too quick to hate. I become like what I abhor.

To hate another human being is to take a worm into one’s own vitals. It consumes life.

"Hate is just as injurious to the hater as it is to the hated. Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Many of our inner conflicts are rooted in hate. This is why the psychiatrists say, "Love or perish." Hate is too great a burden to bear."

Passionate hatred can give meaning and purpose to an empty life.

We need an enemy to give people hope. Someone said that patriotism is the last refuge of cowards: those without moral principles usually wrap a flag around themselves, and the bastards always talk about the purity of the race. National identity is the last bastion of the dispossessed. But the meaning of identity is now based on hatred, on hatred for those who are not the same. Hatred has to be cultivated as a civic passion. The enemy is the friend of the people. You always want someone to hate in order to feel justified in your own misery. Hatred is the primordial passion. It is love that’s abnormal.

Passionate hatreds can give meaning and purpose to an empty life. These people haunted by the purposelessness of their lives try to find a new content not only by dedicating themselves to a holy cause but also by nursing a fanatical grievance.
