The put-downs of his childhood are now capped by the hatred of us, the decent majority. Only this will satisfy our judgment. Only so can we compare the life experiences of similar offenders, discover common threads, and make appropriate social adjustments. While holding offenders from opportunities to further harm people, we can learn how to change their life paths from destructive to caring. Equally, if not more important, by understanding, we can save ourselves from losing our souls, our integrity, in a lynch mob.
Humans lose their humanity in the mob.
They see themselves as judge, jury, and executioner-judging another but not themselves. Those who have let themselves become enraged, and hate, because a fellow human has offended them, act together as a single wild beast.
