There have been studies that indicate the uber wealthy and powerful exhibit more sociopathic tendencies. They are overwhelmingly more likely to exhibit dark triad personality characteristics than average people. Its what allows them to succeed at the level they do. You can't have empathy and do what they do.
Also, just...look at the world.
I agree that a world of vigilantes gunning people down in the streets is not good. But we don't need to be sticking up for or defending the rich and powerful, either. They at the very least operate on a principle of what is best for business which rarely is best for everybody else.
