Because we, if I'm not mistaken, are the only species that naturally, almost instinctively, hates itself. A colony of ants doesn't fight itself, but a colony of humans would.
I take it you've never lived in a neighborhood that allows cats then? - Animals kills eachother, including their own children, even for sport, and none of them have any concept of right and wrong in this regard. There's no punishment, there's no debate, there's not even a single doubt in their minds about doing wrong.
Good analogy though, I can see why Europeans failed to settle North America and the whole human race has destroyed itself while our Panda overlords are trying to save us from extinction. Oh wait.

Yes, that is true, a lot of disease has been eradicated, but there are still a lot more.
My point still stands - How many cures have the rest of Earth's species produced against illnesses?
Here's a hint: None.

But if you think about it, it hasn't really improved the human race as a whole very much. Sending guys into space didn't cure diseases, didn't build colonies (unless you include the ISS, but it's not really a colony) or anything like that.
Yes, space exploration is in its infancy. You mentioned cockroaches as being superior to us, how is their space programme coming along? Who is doing better than us? You don't start climbing a ladder by appearing at the top.

More GOOD than humanity? Ha! For every good thing we have done we have done two bad things.
As we speak, people are getting raped, murdered, abused or beheaded.
Again, noting that animals will merrily destroy the enviroment unless another animal is killing them in large enough numbers, and that animals kill eachother for sport without any social repercussions or any internal debate regarding the morality of it, I would say that non-sentient animals have done the same amount of good as they have built colony vessels capable of interstellar travel.
Tell me, what species defines what good is? What species has enabled the possibility of it ever occourring on this planet?
Millions of animals are suffering too. Do you see them working to solve their problems like we are?
Non-sentient good to evil ratio is 0:Infinity because they are incapable of doing good in the first place.
