I had a good day on a farm kill job. The women who run the nearly 1-square-mile farm wanted to dispatch the animal themselves before I arrived.
More typically, the farmer or owner will have me kill the animals. Some like to be there, some don’t. I can respect that some would want to do the kill: they raised the animals and cared for them their whole lives and I think they don’t feel comfortable giving the responsibility to somebody else.
If you commit to taking the shot, you have to follow through with whatever happens from that moment on.
