This type of behavior is based on "stealing and greed". Why is it called "stealing"? "Taking without permission is called stealing." It's like if you eat the meat of this sheep, the sheep does not actively provide it to you. Unlike the deer in the "Sarnath (Deer Park)", which happily offered a deer a day to the king, in this case there might be no need to repay them with meat. So, if you catch this sheep for no reason and kill it, and then eat its meat, this is called "stealing." So "taking without permission is called stealing". You eat its meat, and it is reborn as a human. Then you become a sheep, and it eats your meat again. This is stealing from each other. If you steal from it, it will steal from you; if you steal its meat, it will also steal your meat.
This person was reborn as a sheep after his death. This is a kind of "Yin retribution"; Yin retribution happens silently and you don't know it, but you have to bear the consequences.
