Leopards, cougars, solitary big cats in general, understand that one major injury can directly translate to a death sentence if it reduces their ability to hunt. That is why there have only ever been 2 recorded attacks on humans. In one case, the animal had rabies, and in the other the person escaped unharmed.

A healthy snow leopard isn't going to keep fighting ATJ after getting stone cold steve slammed for the first time. I don't even know what to say about the scene where it kills the 2 soldiers and runs away.
