What is the danger of power without knowing the truth?

This question is from the field of philosophy, not history. But let’s try to disassemble it.

1. Truth is what exists in reality, regardless of the subjective thoughts and statements of a person.

2. A politician is initially subjective. Even if he is honest and pure, like a crystal, because he is a human being. The bulk of politicians are generally extremely vicious people because the path to ascend to the heights of politics requires lying, betraying and groveling in front of the stronger.

3. Power is the apparatus of violence of the ruling class or group. Its embodiment is the state.
