Utterly Mad

Human beings can sustain damage that would kill a wild animal. A broken leg for most wild animals is a death sentence, for mankind it is a painful inconvenience, even losing a limb entirely was just a more permanent inconvenience, and most of this (non-permanent) damage heals faster than in most other creatures.

Human beings once hunted their food simply by following it without rest or food until the prey was so tired it just couldn't flee anymore.

An animal with horrifyingly toxic saliva is the komodo dragon because of all the **** it eats, human saliva is almost as toxic and for pretty much the same reason.

Humans took one of the few predators that were dangerous to them, wolves, and forced it under its control to assist in hunting, or just to keep around to look nice/be friends with. The other predators we lock in cages so we can point and laugh at them.

Human beings allow themselves to consume so much food that they become incapable of movement, or so little that they become little more than a skeleton, and in both cases it is possible for human to recover.

Human beings are capable of unimaginable cruelty/perversion directed against one another and the creatures around them, while the other creatures of its world don't even really think about committing such acts.

that last one isnt really a "fack yeah!" though is it :/
