“Pigs are hypocrites. They have cloven hooves but do not chew the cud. They are kosher outside but not inside. In any case, there is only a prohibition against owning non-kosher animals whose meat is eaten. It is part of the gezeira against making business out of non-kosher meat(as opposed to selling meat that was later found to be tereif).”
-avik
First of all, pigs are born that way. They didn’t choose to be made that way, nor did they create the rules which allowed them to be this kind of exception.
Secondly, that would imply deception on their part to want to be eaten…which I highly doubt many, if any at all, would actually want. Do you want to be eaten?
