Never allow yourself to forget
You may have escaped being part of the mass formation psychosis, but you should be very careful to ever trust again those who fell for it. They wanted separated from the world, or dead — and it didn't take much for them to be convinced of it.
Every single one of these individuals — and the millions more who expressed the exact same ideas — are evil. And given the exact same circumstances, they will do the exact same thing again.
This is why you must absolutely never, ever forget what kind of evil lurks in the hearts of men, in particular when animated by psychotic obedience to wicked authorities.
