That's interesting. Were they 'sort of decent' people as long as a test didn't come along? Of did they have a core of hate and bitterness so strong that Trump was able to use that and then use them.
My experience in life is that people arent complicated when you get to the crux of them. They have patterns and behaviors that make them who and what they are. People can hide that, or they can act their way around it. But it doesn't change that core being.
Look at any con man. They seem like nice guys but they arent. Everything they do is calculated to screw you out of whatever they are after.
Look at serial killers. Guys like Ted Bundy were called 'handsome, charming guys' but they were really animals.
Look at the kindly grandma. She's not suddenly going to whip out an Uzi and go hunting at the local kindergarten.
The first two are examples of people hiding their true self very effectively. the Granny is what she is and is not going to do a polar flip, ever. Likewise, people that suddenly DO do polar flips in behavior are either undergoing a medical/mental breakdown of the legitimate variety...
Or they were hiding who they were all along.
