Imagine somebody takes you out of your home, murders you, takes out your skin, cuts your body into tiny pieces and then fries you.
That’s what happens to animals when you eat non-vegetarian food.
It’s still okay if the animal has died naturally and you are using its body. But killing animals particularly for your taste buds is more inhumane that you can imagine. Similar is about using animal products. Just imagine somebody killing you only for your skin or teeth or bones.
Animals are not as intelligent as humans but humans really take advantage of their only exceptional virtue, otherwise we are quite similar.
If you cannot stop using animal products altogether, at least, reduce their intake to their good extent so that the their demand reduces in market and thus the need for its supply. Otherwise, animal cruelty has reached heights (you need to watch a few videos about how they live peacefully just before their killing and are shredded to pieces mercilessly thereafter).
