We humans are not perfect beings, often offending others by our thoughtless words or actions. But those who willingly abuse or kill the innocent for their personal gain are certainly the worst among us.
Throughout human history, we have seen such individuals and their followers emerge in the form of armies, brutal police forces, racially motivated militias, religious crusades and criminal gangs. Even today, a number of countries practice genocide and we are now witnessing an indiscriminate attack on Ukraine as the Russian military bombs hospitals, schools and other civilian targets.
Eliminating such behavior requires the collective outrage of human civilization, both within and outside of the perpetrators' country. Harsh universal sanctions, whether they affect our home economies or not, and the facilitation of revolution to oppose the brutal regimes are essential; of course, aid to the victims and refugees is vital and, in my opinion, selective military intervention is warranted to protect the innocent.
