Eddie Izzard has a great skit about mass murderers that I think of when this topic is discussed. We as a society know (or rather, have ideas on) how to handle people who kill 1-20 people just fine, but above that (hundreds of thousands or millions of people), we’re at a loss. “Well done, you must get up very early in the morning.” Feels very similar to these cases where people in positions of power cause enormous aggregate harm and we have no idea how to address it proportionally.
