That interpretation also eliminates the 'norms change' nuance many have mentioned because it's about objectively incorrect assessments of the norms/values of society, as opposed to oft liminal standards.

It takes effort for us to dig ourselves out of our naturally selfish tendencies towards others, especially those of other cultures. Many of our cultures inculcate those tendencies as being proper, when they are anything but, and are, in fact, degrading our world with pollution, waste, and callous apathy to the plight of our fellow human beings.
I do, as ever, however, recommend the works of William Gibson as he always imbues a sense of humanity in his protagonists. The same is true of Tolkien's books, where goodness is detailed and the evil rarely mentioned. The movies were trash simply on account of their changing Faramir's character so unnecessarily. If you want a truly good Hollywood movie, look to the first Equalizer, which Denzel Washington executive produced, whose protagonist is a hero for the ages.
