Ethics and morals

im a vegetarian and soon to be a vegan again, so i guess when it comes to animals im very ethical that being said, ill eat meat if someone else bought it or if its to try something new so its as little harm as possible as my money isnt going to the cruelty, but i dont see why its wrong to eat something someone's already purchased. meat is tasty after all for humans, i dont know i can give or take ethics sometimes im pretty utilitarian with a lot of things, so i'm ok with a minority of suffering if its for the greater good the means justify the ends kinda thing
