I find it difficult to feel responsible for the suffering of others. That's why I find war so hard to bear. It's the same with animals: I feel the less harm I do, the lighter my heart. I love a light heart. And when I know I'm causing suffering, I feel the heaviness of it. It's a physical pain. So it's self-interest that I don't want to cause harm.
