The question really comes down to not our own personal view, but Jehovahs. Human views can range from one extreme to another.
In clothing some go to one extreme of being too revealing, while others, especially in middle eastern countries, go to the opposite extreme of covering every inch of a womans head and body. Humans have warped a balanced and moderate view in both directions. Just because Jehovah rejects the immodest styles does not mean he approves of the ultra conservative.
Likewise, I believe the same is true when it comes to animals. There are some who go to the extreme of abusing them in terrible conditions. There are also those at the opposite end of the spectrum that raise animals on a pedestal to the point that they are viewed as near equals to humans with the same rights.
I believe this too is worldly and unbalanced thinking that is not in line with Jehovahs view.
Jehovah has accepted animal sacrifices from Abel on. He approved of the killing and eating, not only of animals but even their young, such as lambs. Animals have been used as a source of labor from the beginning. The wonderful variety we enjoy among animals is due, largely, to inbreeding them.
These are all things that - in varying degrees - different people might find objectionable or even offensive in modern times. Yet in all these cases Jehovah allowed or even encouraged.
So the point Ive tried to make in this thread is - just because some have mistreated and abused animals in zoos or circuses (captive "domesticated" animals are sometimes abused as well) does not mean the idea of keeping and even training animals for entertainment is immoral in Jehovahs eyes.
