Human nature hasn't changed.
The history of humanity is the history of abuses of power. When one person murdered the next person, when tribe destroyed the neighboring tribe, they did so because they were more powerful. When this abuse happens at government levels, we see everything from people voting themselves higher salaries to Wounded Knee, the Armenian Genocide, and even the Holocaust.
And, most recently, when one person is more powerful than everybody in a nightclub, we see the results.
Human nature hasn't changed since the dawn of time. You should protect yourself from that person who wants to murder you. Protect your tribe from the other tribe. Protect your group from the government.
Protect yourself. Nobody else will do it for you.
