In some countries throwing acid is, like honor killing, a custom among some of the population. Strange that we humans are such a mix of brutality for some and kindness and charity from others. Sometimes within the same individual. The sort of thing Robert Burns expressed so well ;

Many and sharp the numerous ills
Inwoven with our frame;
More pointed still, we make ourselves
Regret, remorse and shame;
And man, whose heaven-erected face
The smiles of love adorn,
Man's inhumanity to man,
Makes countless thousands mourn.


Robert Burns
