All species are violent in some way it is how they have evolved and survived everything is prey for something else all be it to eat, fear, protection or even hate violence comes with all we as humans i would say are as violent as any species it varies on which particular subject you base it on.
Like comparing a household pet dog to a feral dog the feral dog may be much more violent than the household dog your evidence is only as good as the subject it is derived from.
All species have war just not in the same manner we do but that is a fear of each other and a need to protect ourselves from each other so we invent new ways to harm each other because if the threat is dead you do not have to fear it that is an evolution in itself so i Believe we are no better but no worse than any other species even herbivores can fight carnivores and win.
