It's genuinely difficult for me to work out parts of your comment.
> The major Christian view of raising sheep is in the positive.
> but the negative end result - slaughtering
I'm in Australia, in a rural area surrounded by a lot of wheat and sheep farmers, many of them with christian backgrounds, many actual christians.
All regard raising sheep as a positive enterprise that brings in revenue through wool and meat - it always ends in slaughter (save when there's a drought | fire | etc. when there is unintended / uncontrolled death).
That's farming livestock for you, flocks always veer towards an end by slaughter.
Now, outside of any Christian | biblical viewpoint there has always been cynicism about religion, about charismatic self declared prophets leading lambs to the slaughter in holy wars.
It's not a parallel unique or original to the GP comment here on HN .. and indeed it's such a straightforward observation that shepards only invest effort in protecting flocks from wolves so that they themselves can harvest the flock instead of the wolves that I often wonder why christians even use such imagery.
