Humans are corrupt by nature, power enables them to practice some of their desires without fear of revenge or punishment. Why is it that we can kill some animals and consume their flesh? Because we know they can't do anything about it and that no one will punish us for it. Why is it that politicians can lie to you all they want (and screw your life in so many ways)? Because they know that you can't do anything about it and that no one will punish them for it.
