I was being sarcastic about animals being lower life-forms than humans.
I was being serious about hunting humans, because adrenaline junkies are always after the next hit. I can see a conversation at a hunting lodge after a a successful lion hunt drifting towards an operator mentioning that there is an exciting hunt in Afghanistan if anyone is interested in something even more thrilling.
To the hunters out there, surely you graduated from shooting rabbits to bigger game, and surely you dream of hunting even bigger game, like an elephant or brown bear?
Only a nutter would think of hunting humans as game, but unfortunately there are a few nutters about.
As I said before, hunters shoot animals because they enjoy the hunt, and in quite a few cases the thrill of the hunt wears off and they often become animal protectors.
And animal protectors who used to be hunters usually make the best game wardens and rangers.
When I was quite young I shot animals because I enjoyed the thrill and excitement of doing so, plus peer pressure (although it wasn't pressure as such) had a part in it.
In later years I still shot animals, but didn't get any enjoyment out of it, at that time it was a job and it was about as fulfilling as a farmer who puts sick sheep down.
Shooting of our fellow humans for most of us is automatically repellent, and few would to it for sport.
I have shot two humans in the past, they didn't die, luckily for them because I sure as hell was trying to kill them.
I didn't get any enjoyment or thrill out of it, but nor do I have any regrets other than the fact I didn't use a more powerful weapon.
The point though is there are many motives for hunting and killing, sone bonafide and understandable, some not so much.
