Good and evil.

You don't need to be a Satanist to know what they believe, just as you don't need to be a Tolkien enthusiast to read The Lord of the Rings. And where is Darwin's theory now? Even in school, they say that it is mostly incorrect, and Darwin himself admitted its inconsistency before his death. Hitler took any more or less convincing and logical arguments from others and incorporated them into his ideology. Regarding the question of Good and Evil, there is indeed subjectivity. When talking about hunting, it is true that people get Good (food) from hunting, and animals experience Evil (death). Burning progressive scientists during the Inquisition was considered good for most Catholics; they were firmly convinced that they were doing good, but that doesn't mean it was actually good. Each person judges through the prism of their own consciousness, so the good of a Christian and a Muslim is different; they have different consciousnesses. In war, everyone has their own truth. Wars arise from the thirst for advantages and the desire to protect oneself. In modern consciousness, it is considered impolite even among the inhabitants of one's own country to say: "We are going to war for plunder," so things like preemptive strikes, the division of the world during the Cold War, and pseudo-searches for nuclear weapons appear.
