This is true. You can say whatever, but human beings are by far the most lethal species on planet earth. Do you see any animals or fish dropping thermonuclear bombs and annihilating cities? Nope. Even before the dawn of mechanics, we used teamwork and cunning to bring down huge animals like mammoths.
If we were a bunch of leaf-chewers, we wouldn't need to be so dangerous. Hence we'd be much less intelligent, and have different physical features (more balanced towards defense, e.g. bony plating)
