Consider this: When humans gather in large groups voluntarily, it is almost always a peaceful happening. If violence does erupt, it's due to a small contingent of agitators, the police (themselves following orders), or there is some other extreme factor (like scarce resources, or a flash point has been reached due to extreme government measures). I've never warred with my neighbors, fellow shoppers, others sharing the parks, on the highway, etc., and they all pretty much seem to be getting along ok too. Doesn't look like a warlike species to me. Looks pretty much like folks just generally get along. If the species was truly warlike in nature, we would have long ago have eradicated ourselves from the planet, and saved the future AI's the trouble.
When humans gather in large groups involuntarily, it is almost always a violent scenario. But who conscripted them, and cui bono? Hint: It's never the farmer, nurse or small businessman.
Sure, humans have the capability to cause harm. So does almost every other species. Any horse can be made to bite or kick humans at any opportunity, and any horse might bite or kick in some scenario, but who will label the equine species "dangerous and unpredictable"?
