Seeing people in power who abuse and exploit the vulnerable and defenseless can elicit different reactions in us, like fear, despair, or anger. Sometimes, the reaction can be that of wanting to understand - a certain curiosity, of how such a morally bankrupt person can exist among us. The latter can be likened to witnessing a train wreck or a car crash and not being able to look away.
At worst, such misguided curiosity can lead us to become stuck, like a deer staring into the headlights of a car about to kill it. We obsess with media depicting mass murderers, serial killers, pedophile criminals, rapists, and sexual abusers. We have engrossed ourselves to much in depictions of twisted realities in the form of self-looping psychological narratives that lead its audiences to nowhere but a steep fall from a meaningless cliff. In short, we begin to consume slop in the guise of exploration and learning.
We become too slow to recognize that the best we can get out of examining a morally bankrupt person's life and the times that gave rise to them is to learn from the mistakes committed that bred such hate, so that we may never repeat them nor propagate the illness of moral bankruptcy.
