Yes, humans are capable of wars. But also, humans are the only predating superior animal capable of forming crowds of thousand individuals without a single fight. Try to make a crowd of thousand monkeys or dogs and see what happens.
You can't have the good moral without the "bad moral". The same capacity that can make humans evil, can make humans saints. That's the moral capacity, the capacity of choosing the way they act beyond what's supposed to be the natural behaviour. Other animals have a bit of this capacity to some extenet, but not enough to say they have free will like humans do.
Before the great population explosion, deforestation and European incursion into africa, back in the 1700s there were tales of "kingdoms" of monkeys numbering in the thousands. There are also accounts by of ape (iirc gorilla) group numbering close to a thousand. Go back 2000-3000 years and who knows what you'd find.
Tigers used to selectively and intentionally conduct warfare on humans in india until the 1800s. That changed with the introduction of the gun and hunting campaigns forever decimated their numbers, and imprinted a fear of humans into both their social group and genetic psyche. Competition for resources, never ending encroachment in their territory and hunting campaigns caused them to engage in behavior only seen by gorilla troops. They would wipe out an entire village of over a hundred for example, not eating them, simply killing everyone.
Humans can modify their behaviour by the mere power of ideas and reasoning, for the good and for the bad. This is the moral power of the human being. The rest of animals are not moral. They just act and they can learn to act differently, but just by learning different behaviours, not by reasoning and taking moral (good or bad) decisions.
What I meant is, once we are a moral species, we need to reason in order to find the best behaviour. Because we can.
It's not glorifying. It's pointing the obvious difference between humans and the rest of the animal kingdom.
Pointing human weaknesses won't change the fact.
I would say countless animals can reason and alter their behavior via analysis of a situation and decisionmaking overriding some imprinted "instinct". I don't know where to begin...
Take the raven story in scandinavia. The raven’s intelligence and persistence are fascinating to observe. In Scandinavia, an unattended ice fishing line turns provides an easy meal for a clever raven — until the frustrated fisherman finally discovers the thief’s identity.
- Raven figures out how to manipulate fishing line (tool) (other example of tool usage using twig/sticks in beak to spear worms burrowed in tree trunk)
- Raven understands the purpose and benefit of waiting for the human to leave before attempting to extract fish.
- Raven realized what the fisherman was doing by pulling up the fish.
- Raven learned (and understood by the time of the video recording) that a tug on the string meant that a fish had caught on the hook/sink. As soon as the string started to get tugged it flew down and pulled up the string.
