"The faults of a generation rest with it's heads and leaders."
But each person of a generation has been brought up by parents who have influenced what that child becomes ready to do and who that child becomes ready to accept as a leader. And the heads and leaders possibly were brought up by moms and dads possibly similar to those who produced the generation.
The ones at the top can be the tip of an iceberg of others having similar character so all are available to do something with each other.
You can not keep the tip up there without the mass of ice below the surface to support it.
In Germany, Adolph could not have done things he did, unless there were numerous psychopaths capable of welcoming him and their opportunity to do what they did with him. Ones capable of obeying him had already been produced, before he showed, and they already had developed so they were capable of doing what they did. So, they helped each other.
Of course, previous leadership had kept them in check; so yes to some extent it was the fault of Adolph who turned them loose. But many people cooperated with him; they chose to do that. Of course, there were ones in denial, possibly because of what they wanted to be true, though . . . not caring about others as themselves, but only their own country and ambitions, maybe. So, their own character and development helped, I would say.
Part of that might have been how German laborers felt they were being cheated; and they were willing to kill in order to have work, and Adolph had people killing Jews in order to get power. And in the United States, at different times ones have been fine with killing people of certain groups, in order to keep or get what they wanted > Native Americans, Mexicans, kidnapped Africans, and now ones kill the unborn in order to have what they want. And now we see how certain ones are fine with indirect killing > there are ones who want to work; so they are fine with others dying of COVID-19 so they can work.
But during the Capitol event we did not see tens of thousands of people each killing people, and right now there are not tens of thousands fighting and killing and vandalizing. I think that crowd easily could have done a lot more, if all were committed to violence and use of force. So, I'm not sure they all were there for a takeover.
Plus . . . already . . . in the United States, checks and balances were in place and helped, so Donald was stopped, I would say. Also, there's the you can't fool all the people all of the time thing.
We already see how humans are capable of believing exact opposite things, or ones are capable of outright lying against the correct group.
Ones did that with Jesus. Ones knew the truth about Him, but they even bribed soldiers to lie and say they were asleep while the disciples stole Christ's body. So, yes humans are capable of deliberate conspiracies, while others can believe maybe whichever conspirators they want to believe, depending on who promises them what they want to hear.
So, may be I need to be wise to how I can fool myself, so I am not so ready to jump to believe people I don't even know.
