My point is some people are killers. They hate humanity and they love to kill. Whenever there is some sort of crisis where violent groups or people can ascend to power, many times the most violent people or groups do ascend to power. And they start their killing. They might have some sort of ideology (communism, Nazism, fascism, humanism, etc.) that they claim guides them, but basically they like to kill. Because they’re psychopaths first, ideologues second.
Yet ideas do have power. One might use the Bible to justify slavery, but it’s not the basis of Christianity (or Judaism for that matter). One might also distort the Gospel (and Democrats do) to justify socialism. But once God is taken out of the equation, and the idea of survival of the fittest takes hold, abuses are bound to happen.
