RE: I worry that its brutal...help me please
Another thought - I think farm hunter hit on it - death is death to an animal, but I don' t agree with not hunting. In fact, you should hunt this year. You have plenty of season left (if you have late bow after gun where you' re from). Hit the range a few times - if you are not shooting instinctively, what practice you' ve put under your belt won' t go away. It' s like a gun - if the pins are on, you' re on.
Think about it this way: nature in itself, is extremely brutal, far more brutal than we could ever be in my opinion. Watch the nature shows, Discovery, Animal Planet, whatever - lion eating their young, killing by suffication, poisens, attacking and eating while still alive, critters eating each other, taking the young, etc........ Think about it, nature itself is brutal.
So really, don' t think about it and just get out there and hunt.
