I think we have to understand that hatred is a bad thing, every religion teaches us to live in mutual respect, have love among fellow human beings, not even hate each other, by saving this it will cause various conflicts, even with hatred can make people kill each other, so let us get rid of hatred and create affection among others

Any religion, plus common sense, plus history lessons.
In a broader sense, any hate (including self-hate) is a disease.
Though I may agree that self-hate is the worst of them all as it triggers hate to everyone around. And if G-d forbid the self-hater has any power over others they become tyrants (on small or big scale).
