Individualism serves to allow atrocity. This is obviously not the ONLY thing it does but it is one of the things it does.
It allows us to blame presidents instead of the governments, CEOs instead of companies and, Popes instead of religions.
Note that all of those are people taking bullets for system. This is not a coincidence any more than the golden ratio.
Perhaps we should consider universal culpability. Ultimately we allow these things to occur, are we not all partly to blame?
We should focus on prevention and understanding, not blame and punishment.
