While some people are really good, and some really evil, most of humanity has thos duality. They love you when you're successful, or for your popularity. But it's amazing how easily they can really turn their backs on you, even for no good reason.
There is an idea that: 'Nazis were regular people.' By some accounts the most common method of those millions who were murdered in the Killing Fields was by pick axe, to save bullets and money. The immediate reaction of that for me was the callousness, torture. But if you stop to think about it, how personal of a method is that? This was not just mass genocide, and it was not industrialized. It was carried out by masses of people with their own hands in a personalized way.
After my traumatic experiences with psychopathic cheating, abuse as an adult, now every time I hear or read of psychopathy happening today -- what is essentially just one group of people abusing, exploiting power over others for personal gain at the expense of others' liberties -- I think "Oh my God, we all need to wake up and do something." It feels like every day there is some new form of tyranny I learn about which is happening today, which is considered so ordinary that it is allowed to persist. Sometimes they are obvious evils, such as The Insulin Racket, Abu Ghraib or the Collateral Murder leaks, for example. But other times I see some of these group tyrannies have propaganda machine behind them which are not different from other forms of facism or tyrannical power structures, such as I think is the case with Big Pharma or Wall Street.
I think there is a crazy duality with humanity where we have abuse, tyranny always so close, and tolerated. We all know what it is -- that it is evil. We all hate it, and are ashamed of it. We always criticize it when it is at a distance, but then nobody is doing anything about it just as past generations did as well.
