For me, morality exists in respect to the harm principle. The responsibility of the harm comes down to whether the human is aware/recognizes the harm as such. Is it always bad to cause harm? Religion requires there be a God that approves and disapproves of types of harm, and that it be obeyed. Why not discuss what harm individuals are willing to accept instead? This might be objective, or it may just be a construct of human society, of human perception. Good is relative to the human after all.
