I asked him

whether he thought, given the fact that we were
both trying to be Christian people, you could ever justify the
use of violence. He told me that he believed violence was
wrong, but If someone left you no other option other than to
hit him, then it was their karma, it was meant to be. He said
that he felt they were sent by God to be taught a lesson and
he would give that lesson as gently as possible.
Some people need a poke in the eye to show them the right
direction, others simply need pointing in the right direction.
It is a question of having the wisdom to know when to point
and when to poke.
