They are getting more due process than they give their victims, which are also fully sentient, intelligent beings.
As far as I'm concerned, you hunt down a gorilla, elephant or similar with a high powered rifle, trap, or poison their water source, then use a chain saw to hack out their tusk or hand to sell, you've turned in your human-card for good.
At the very least, they've signed up for "Live by the sword, die by the sword". (and they at least have the ability to shoot back at their hunter, more than the elephants/gorillas have)
