Which takes me back to my point again, you're thinking how an animal should behave, from a human point of view. Animals might not view it that way, and may view it as an accepted part and parcel of life, and something they know could happen to them, but it may be a way of life that they like, and they might not have it any other way. But you think (thinking from a humans point of view) that it's cruel that a lion should chase after a deer, and that this poor deer is frightened and has to run for it's life, and that an animal should have such instincts. Therefore according to you, the Creator of such a "travesty" must be cruel, sadistic, and morbid, and He got it all wrong.
We would see the diversity in the world, the different ways of life amongst the animal communities, their interconnections, including what we don't fully understand, as signs of an All-Wise Creator. Animals have not been created humans. As animals are resources for us, some are resources for each other. They cannot very well keep farms and slaughter in the human way. They also have a way, which is different to ours, even if we don't understand it or it doesn't sit well with us. As we eat certain animals, so do some of them. They don't hunt for amusement, but to eat.
How they appear to behave naturally with each other in their habitats should not be a cause to reject belief in the existence of the Creator. These animals aren't even aware that someone is jeopardising their belief because of them.
There are things in the world that may not sit well with us, or we don't understand. That does not imply absence of the Creator, or that the Creator is cruel. God is not a thought process, but a reality, that existed before we did, and will still exist after we die. We are the ones, that have a fleeting existence, and indeed once we as individuals did not even exist - we were nothings, nobodies:
Has there not been over Man a long period of Time, when he was nothing - (not even) mentioned? (76:1)
