Everybody wants to be Hitler
The man who believes in God is like a man who is asleep in the back seat of a speeding car. If he awakes suddenly, he sees someone he trusts driving the car and returns to his slumber.
The man who does not believe in God is like a person who is asleep in the back seat of a speeding car. When he awakes he sees no one driving the car and clambers over the seat to grab the wheel himself.
The problem is that the "car" is the world. A friend once summarized the book, "It takes a village to raise a child" as the federal government is the village and you are the child. There are many reasons people have for trying to gain control over others.
1. Greed. People like to have things. People do not want to work to build things when it is so much easier to take things from others. From plantations and colonial exploitation to illegal aliens and the slave markets of Rome we can find people saying, "How can I screw my neighbor and get rich".
2. Conformity. People do not like to feel uncomfortable. Differences make people uncomfortable. Killing people who are different makes everyone feel better.
3. Vanity. We all like to think we are the smartest and best people in the world. It is only natural that some of these "best" people would go into journalism so that they can instruct the inferior people as to what they should think and do as well as expose the recalcitrant to public ridicule in order to force compliance.
4. Zeal. Some people give themselves over to a religious, environmental, political, or ideological jihad. For them, there is nothing more important than what can be achieved with a car bomb, crusade, or firmly worded letter to the Times.
Regardless of the motive, the first step is to gain power so that others can be controlled through force. The path to Hitler-hood is not achieved by following the path of truth. It is realized by doing and saying whatever you have to so that you can get control.
There are some Christian denominations that instruct their people to contend for control of the steering wheel. A more Biblical view is to trust that God will sort through the mess the world is in and will straighten it out. For us to think we have to fix the world is a measure of how far we have drifted away from God.
