There is nothing wrong with violence in itself. In any particular case, whether violence is good or bad depends on how it is used and the purpose for which it is used.
Humankind has to get out of violence only through non-violence. Hatred can be overcome only by love. Counter - hatred only increases the surface as well as the depth of hatred.
I have an implicit faith ... that mankind can only be saved through non-violence, which is the central teaching of the Bible, as I have understood the Bible.
