We have rescue dog (abandoned on the street) and it seems to have a notion that violence within family is bad.

I was quite surprised to see that when I mock threatened my wife with a broom in his presence he jumped in to block. Not only that, he took the broom away from me and secured it away. I initially thought it was play, that he wanted to play with the broom. Seems he was just interested in separating me from the broom. He is our household saint.

We have a much younger dog (another rescue) who is not very nice at all to our saint. However, if my body language has even a hint of a threat to our little devil, he sure gets perked up and ready to protect.

This probably comes from pack behavior instinct. Fights inside a pack is bad.

Nice story. I believe that dogs are capable of moral judgements too. The idea of 'evil' is a human idea though.
