I think that's called acceptance and maturity. The first time I had to stick a needle into someone's vein I thought it was a horrible feeling and I felt like I would hurt them, botch it up, make them scream, or worse, hit an artery and have to staunch the flow of their life's blood from pumping out on the floor. But..as time goes by and you do it hundreds of times, it's just a job that is best done fast, done well and gotten over with. I got good at it and I'm glad I didn't let that first fear keep me from practicing until I could be confident that I wouldn't hurt people when I took their blood or gave them an injection.
That's the whole thing with butchering chickens too...it's a hard job, a dirty job and it never feels right to take the life of a warm, living creature with your bare hands. But then you do it, you get good at it and you're glad that you are proficient at it so that the bird doesn't suffer, die of illness and old age, etc. It doesn't bother me anymore either, though I still don't really like to do it...I'm just glad I know how and I can give my birds a good life and a good death and that's all the matters in the end. It's all a part of good stewardship and it makes me proud to do that well and honorably.
