Nothing is black and white.When i was working, one of my co-workers was ex-Scots Guard and when he was based in Northern Ireland he was shooting at IRA…when on leave, he was at Celtic Park singing pro-IRA songs. Another co-worker, an ex-RSM, the highest NCO rank and perhaps the most influential in any regiment, once told me that come the Russian invasion he and i shouldn't really worry …for all that will happen would be instead of a crown on our posties caps, there would be a red star…and we still be doing the same fucking job. But i understand the tenet of your post…a job can dehumanise. I recall a union official responsible for the butchers at Halls of Aberdeen telling me he was always terrified of those slaughtermen and again the co-workers i knew who had worked in abattoirs were all a bit psycho from becoming immune to the sounds and sights of suffering sentient animals.
