How Can You Settle a Human-Animal Moral Dispute?

consequentialism and deontology
Be a consequentialist or deontologist
How can you settle a human-animal moral dispute? Be a consequentialist - value a good outcome and aim to make the best consequences for the most good. OR. Be a deontologist - respect your duty and carry out your obligations (regardless of consequences). What if outcome and duty match? Odd - but a happy solution!
