Isn't it better to cut off the animals head completly than cutting half of their throats (for food)?

How is it not better than religious way of cutting? The animals would lose consciousnes faster if guillotine method was used.

Guilotine removes the head from body in half a second, which is better than religious way of cutting half of their throads. What is more, this also happens in a slower way with a man cutting their throads with a knife of his.

A modified guillotine for animals should be a sin or haram. Aside from religions, I don't see any reason not to do it for a better death.

I would much prefer to be guillotined than a man cutting half of my throat with the knife of his like animal slaughter if I am to be executed.
