Well.. many years ago when I first started hunting and shot a deer. I felt sorrow initially, but gladness afterwards for having killed a deer. My father, who spent three years in the South Pacific never picked up a gun after WWII (but knew enough to teach me to shoot correctly, was his only exception). I explained to him how I felt after shooting the deer. And he told me, that is a good thing, it just means that you have compassion.
Nature is cruel, what you don't see on Walt Disney or the Nature channel is that prey animals such as deer and elk that are taken down by predators, are being eaten while they are still alive. OUR SITUATION IS - Man has a Conscience and we recognize our responsibility - and that is a very good thing.
Here is a little prayer I keep in my pack -
A Hunter’s Prayer
0 Lord, I am a hunter
And life I seek to take
But let me not attempt the shot
Beyond my skill to make
For Lord they are your creatures
Given for our use
But each one falls within your sight
They're not for our abuse
And when I loose my arrow
Please guide it swift and true
Or let it miss completely, Lord
That pain be not undue
A clean kill or no kill, Lord
Such is my heart's desire
Give me the skill to make it so
Or let me hold my fire
And when my time upon this earth
The days they are fulfilled
Grant that I may die at least
As clean as those I killed
