I doubt there's a person alive who invulnerable to all exploitation, scams, lures, manipulations. Smart people join cults. Strong people revert back to toddler age when talking about their therapists. I see public scams and demagogues with worshipful followers. Despite my vigilance of maybe a half dozen cons in my life, I still can be fooled by someone's act colluding with my insecurities and needs.

I think it's important to learn from mistakes, remedy what's possible but also forgive ourselves and others.
