Is torturing another animal immoral?
It hasn't been for many people for the vast majority of human history, even including humans as other animals.
There aren't any lions in North Africa because the Romans killed so many of them for public entertainment. Spanish bullfighting is even the continuation of this Roman spectacle.
You still haven't explained the mystery of how humans' 'innate morality' managed to remain hidden for the vast majority of their history.
If we have an innate morality, it is in the sense that chimps or dogs have an innate morality, not in any kind of modern tolerant humanistic sense. We can create better moralities but to call them innate is simply a piece of irrational, faith based wishful thinking.
