We may need to try and be better than them. I think that is the point, at least for me.

I'm no vegetarian, and I like to indulge myself with some 'pulpo a la gallega', But one thing is killing an animal because we are at the top of the food chain, and another thing is killing in the name of sport or culture.

Animals don't have the mental capacity reason about moral philosophy, so we can't really judge them for not behaving in another way. But we humans have, and yes, we can judge other humans for causing unnecessary suffering towards others.

Great point. Do you think it is immoral for the animals to do these acts? Should we as bystanders have any obligation to prevent this from occurring?

such as what?
