This tragic outcome is called Karma by Buddhists Christ called it "As you sow, so shall you reap." Nobody except small children and the insane is immune from reaping their misdeeds.
And that includes me. Hence my morning prayer: "Dear God, just for today, please stop me from behaving like a complete ars*hole." I believe that enlightenment follows a prayer for help.
