I think, and obviously it’s from an external perspective, that America’s biggest problem is that revenge seems to be a cultural norm.
It’s so seductive and so easily identifiable, the bad guy does bad things because they’re bad and if we’re not bad then obviously we’re the good guys. It’s so easy to think in those terms because we’re unique, unique finger prints, unique personalities and free will, so being bad is a choice and the bad guy deserves what he/she gets, even death is too good for them if they’re bad enough.
What’s more difficult to understand, is that whilst every human/animal is indeed unique, a dog still acts like a dog, a penguin acts like a penguin and a human acts like a human and each are subject to its life experiences; a kind/good person had understanding parents that treated/taught them well, including the consequences of bad behaviour, whilst the bully/bad person had uncaring/abusive parents that either beat them or maybe spoilt them and failed to teach them reasonable behaviour.
Now I’m not suggesting the bad person should be let off without consequence but a little understanding of the above should at least allow them a little compassion and a realisation that anyone can be good or bad, add fear to the mix, without understanding you create a black/white world where revenge is the only sensible option.
