Re the moral dimension: I think killing living things is a form of violence. Some forms of violence strengthen the actor (eg exercise, sports, constructive disputation, butchery for subsistence) but some erode the soul. Uneccessary cruelty is corrosive to the soul and most people cannot commit acts without lessening themselves.
This sounds very airy fairy and I have only come to these views after the age of 40 as my blood has cooled. I am ashamed to say that I saw Avatar again and realised the blue alien was saying the same thing.
Sadly enough some meat prepared and labelled as ham is in fact lamb or beef. Check your labels carefully.
