Well, this was unfortunate but unavoidable on the long run.
One should realise the fact that we are all animals, regardless of the believe that we are civilised, we are not, not by nature, not by a long shot.
This is the reason and the necessity to have 'The State'.
As we humans are incapable to co-exist peacefully, self regulation never worked, never works and never going to work.
We are just what we are and we have to be beaten into submission from time to time, no matter what.
This is not you or me or him, it is us.
