Zevists and the Gods care very much about animals, I might not be the most qualified to speak on this topic as I'm not a nutritionist but I do think diet is a personal choice... Veganism can be dangerous because people can get nutrient deficiencies and impaired physical and cognitive functions. I think everyone wants all the animals to be happy and this comes when we take care of them and their environments (not raise chickens in batteries and livestock must live in clean conditions, etc).
My understanding is that meat is very good to have in our diets, our pets eat meat and so do the carnivore animals. We must treat all life respectfully and eat in moderation.
We have to be strong and healthy so we have to take care of our minds and bodies - Eggs and milk are a good source of protein which our bodies need to build and maintain muscle, low muscle percentage can lead to dementia and frailty. It's best to have a well-rounded diet that helps you feel full and energized.
