I consider non-violence to be compassion in action. It doesn’t mean weakness, cowering in fear, or simply doing nothing. It is to act without violence, motivated by compassion, recognising the rights of others.
If pity was always equally alive and acting in all individuals and in all circumstances, we could do away with moral. Unfortunately, it is not compassion, but rather it's contrary, selfishness, that act most strongly in us.
A man of good sense but of little faith, whose compassion seemed to lead him to church as often as he went there, said to me; 'that he liked to have concerts, and fairs, and churches, and other public amusements go on.
I think there is a complicated side effect to overcoming evil in that we are forever changed by it. I think after we ingest some of the cruelty of the world, it takes years off of our lives, but it also gives us wisdom and a little grace, hopefully a sense of compassion.
When the only bond between close friends is attachment, then even a minor issue may cause one's projections to change. As soon as our projections change, the attachment disappears, because that attachment was based solely on projection and expectation. It is possible to have compassion without attachment, and similarly, to have anger without hatred.
