Saying 'eating animals is yummy' as a justification for killing them is pretty much the same argument as saying rape is OK since it feels good to the rapist. Civilized people require more than sensory pleasure to justify behaviors.
Snake spirit animals represent healing. Transformation, life changes. As a snake grows it shakes off its old skin. So in order for it to grow, it must leave behind something that is hindering them. they’re typically content to bask in the sunshine of life!
