Killing animals for meat is not torturing, you have the wrong idea. Have you heard of a gun? One rightly-placed shot and the animal is instantly dead without pain. You really live under a rock. There are a lot of ways to kill animals, without torturing them, using a wide variety of weapons. After the Flood, God himself told Noah to kill the animals for meat to eat.
Let me show you the difference:
Killing is just striking someone down as quickly as possible, to cause death as soon as possible
Torture is when you deliberately cause painful deeds to someone, without the intent of killing them right away but instead prolonging their suffering
