A great discussion point on the ambiguity of good and evil, and the rather narrow idea of “good” and “bad” individuals. This considers the reality of the moral high ground concerning how a “good” person may act out upon a “bad” one and our acceptance of that as a society.
“Each act of vengeance is more gruesome than the last. It isn’t enough that the bad guy is prevented from doing his bad deeds; he must suffer as much as possible. It is as if the existence of evil- or something that can be designated as such- provides a safe haven for the good to engage in evil. It’s a safe space to indulge in inflicting harm, to experience the sublime of suffering.”
-M.E. Thomas, “Confessions of a Sociopath”
