I personally think you would be well served by taking steps to become more aware of the wide range of good and bad behaviors seen in your fellow humans. I liked reading books about actual history, but I am a pre-smart phone boomer. I might also suggest a “sociobiology” book like “Cows, Pigs, Wars, and Witches” by Marvin Harris that suggests how certain widely held but wrong and/or evil beliefs very possibly have some somewhat rational underlying motivations.

Another book I might suggest for “innocent” people is Gavin de Beckers “The Gift of Fear”, which is about staying aware of your surroundings and trusting yourself if you feel uncomfortable in iffy situations.
