When power goes to people's heads

I often wondered why some people go truly out of control when success, money, and power go to their heads until one day I read this: “Money doesn’t make you an asshole. Money just makes you care less if people know you’re an asshole”… How true.

So why does this happen?

Is it because the feeling of power has been found to have a similar effect on the brain to cocaine by increasing the levels of testosterone and its by-product 3-androstanediol which in turn leads to raised levels of dopamine, the brain’s reward system, which is very addictive?
