Conflict, dialogue, compromise, misunderstands, differences and strife are what make humanity a great thing. If you homogenised the world in such a way that no one ever wanted for or fought over (physically or verbally) anything then you’d be diminishing us as a species. Absolute peace and unending supply is not paradise; it’s stagnation and slow death.|
That does not justify killing, of course, but we have to accept that death is indeed a natural part of life. Not only natural but absolute essential to life. That does not mean we SHOULD cause more death than we must (just living causes death; even plants are alive, veggies, so everyone “kills” to live) simply because it makes our lives more convenient.
