I don't know how you can think that the animals we eat have a good enough life than that it's better than if they weren't born. Imagine being only into cages without social interaction, fed horrible junk, only to be killed a few months later for food.

I'd definitely choose not be born over being born as cattle.

By that logic it would be better no animals would exist at all. If you think cattle suffers, you should watch a live dear being torn by wolves.
