I feel the same as you do. I've never been a trophy hunter or sport hunter, I've ate everything I've killed.
And the defensive part is a necessity nowadays. I had an attempted home invasion when I was still living in Colorado and by the grace of God, I didn't have to shoot him. It went like this, knock at the door, I answered it and some big stocky guy asked if he could use my cell phone because he was broke down.
My Spidey sense started tingling (lol) so I said no, and it was on. He attacked and tried to force his way in. We fought on the front porch, busted the screen door glass, and then we broke apart, which gave me opportunity to draw my pistol which I pointed at his face, expecting him to run...
He didn't. He looked at me for two or three seconds, then started towards me! (What kind of idiot advances towards a drawn 45?!)
That's when things went into slow motion. I didn't want to shoot him, and the cops frown on warning shots. But I reasoned, do I have time to fire a warning shot into the grass (while retreating into the house) and still have time to shoot him if he still kept coming? I figured I did.
So that's what I did. Fired a single shot into the grass beside the porch, while retreating. It worked. The sound of the shot made him run...and I began praising God that he did.
I've read that shooting someone affects you and changes you. I don't want that. I did everything right. Repelled the invasion and without shooting him.
