So here's one thing: all humans are the same.
It doesn't matter how evil you are, you are not immune to guilt, when you fuck up millions of people you are going to be affected. They (corrupted rulers) are probably on multiple drugs and pills to patch up their conditions.
Wrong. They may not experience guilt and shame the same way you do, they may have their own beliefs and sensibility levels but nobody is immune to guilt the same way nobody is immune to physical pain. Nobody is born a malignant narcissist or a money addict. They are compensating.
