For sure, chimps are pretty violent critters. And look at those teeth, they are VERY similar to ours, even down to the midsized canines and bicuspids and the number of molars, good for biting, tearing and grinding.

As regards to violence, hunting is violent, but farming can be peaceful right until the last minutes. And anyway, the animals we routinely eat are highly bred to be dependent on us, keeping them and working them and slaughtering them is literally what they are born for. When they escape into the wild within a few hundred generations they are back to their more wild, self-reliant form.
