I had a little theory about health that might relate to animal cruelty.

Us humans have some similarities with pigs, if one is to examine a pig's internal organs, they are almost the same as ours. A human being if suffering in emotional stress and experiencing alot of pain, his endocrine glands secrete alot of chemicals and hormones to the blood to enduce reactions to the body. Surely the pig does the same, imagine when the pig is suffering everyday in a pitiful cage or when it knew he is going to be killed when the butcher is slicing its throat to fill a bucket with its blood before the pig gets cut open, its organs run in high alert in its struggle to survive and pumps all these chemicals to its blood.

I am not sure if this affects us or not but we rather eat meat than pig hormones right?
That's why I think when you kill a pig for its meat, the humanely way to do it is to knock them off with an electric prod to the brain might be a good way.

Passion is anger and love combined. So if it looks angry, give it some love!
