This is a worthwhile thought exercise. I'm not sure why people are down-voting you. I thought about it some and I think the difference is that for humans, we have other less horrible choices than animals. Our choices aren't (a) get eaten by wolves or (b) starve to death (c) get shot by a hunter At end of life we humans can get palliative care for example. I sympathize with your rebellion if you will, against the cruel choices nature has presented the other denizens of our planet. However, one must consider the reality not what we simply wish the reality was unfortunately.
