Depends what you're hunting, not everyone kills with a gun. Fur seal pups for example are beaten to death with large hammers, sharks/whales/dolphins are shot with harpoons and dragged onto a boat then are killed.
Some guys were hunting/trapping wild pigs for game, the poor pig had it's trotters sawed off while it was still alive.
Some boys at school beat a baby bird to death with a mini shovel, they picked it up by it's mangled neck and threw it at some girls before cracking a laugh. That made tears come to my eyes, I don't see why you wouldn't want to have sympathy for that baby bird.
That's animal abuse, not hunting @ the thing with the baby bird.
Not all hunters are like that @ the pig statement.
I don't exactly agree with the way marine life such as, yes, sharks or whales or dolphins. I don't care if they're being hunted, I don't exactly like how they only use one part such as a fin when it comes to sharks. Even so, yeah, they're harpooned and then dragged onto a boat, but they aren't even in pain for that long. It's just.. harpoon the animal, drag it onto boat, kill it quickly.
Seal clubbing it kind of.. meh. I don't see why they should club it to death instead of just shooting it in the head.
Also another thing. People need to stop assuming hunters do what they do as if they hate animals or enjoy beating things to death or whatever. Go ahead and flame me, but I'm pro-hunting.
