If you just look one in the eyes or bond with one a few moments, you will never eat them.Cows are fairly intelligent and have emotional depth. They can display fear, anxiety, empathy and other complex emotions. They have individual personalities (some timid, some bold, etc) and can bond with humans. Most cows basically trust us, as domesticated animals do, and the way they are slaughtered, especially in this video, show horrific pain and betrayal.
The cow in this video particularly knows its fate and struggles—seeming to still trust those slaughtering it to the end.
The same might be said for pigs, which are extremely intelligent and playful although less docile. They can be loveable and sweet and playful, and can be trained.
