We don't have the capability or will currently to do much about it in a way that won't devastate the food chain, and thus the environment. So while it's sad and unfortunate, there's not much we can or should do about it, on a mass scale. If I personally stumbled upon a (small, not threatening to me) predator attacking a prey animal, I would personally intervene.

This seems pretty intuitive. I think most people have roughly the same mindset.
