You're missing a lot. I'd suggest we go hunting together sometime so you can see.
Life is about decisions, not just "perfect, no-lose solutions," and sometimes we must make painful decisions. Plants emit ultrasonic "screams" when cut, yet few vegetarians even suggest eating only the dropped fruits of the earth. Likewise, nature is very cruel...and yet sportsmen often give creatures a life that is less cruel than they'd otherwise have, from habitat preservation to population protection to a more swift and painless demise.
Might I suggest with just as much benevolence as your posts, that you are ignorant and could use some broader and deeper understanding of the topic.
You don't say what kind of doctor you are. I have my guesses. Mind sharing?
