Search pubmed for empathy. People who have it, have it, those who don't aren't going to build it, because it's brain structure (anterior insular cortex). If you want to make change, you have to care (and be willing to expose yourself to the costs involved) to put yourself into positions of power to have more leverage to effect change at scale (to prevent the events from happening you mention; do you want to know about them if you cannot change them?). Do you care enough to seek power you don't want but need to make the change you believe in?

"One of the penalties of refusing to participate in politics is that you end up being governed by your inferiors." - Plato

This sounds like doomscrolling on steroids.
