The Bible does not state conditions for Lev 17 only the provision for restoration if a native or foreigner ate a dead animal or one torn by a beast.
Why would such a person do that or how could he do that when the law forbade it? The Bible does not say. The Bible does say in Numbers that doing something ( that was forbidden) deliberately was a capital offense.
( I posted something yesterday that did not post through so if that posts in the future it is after this dialogue.)
Something that may be a factor and needs to be considered is the definition of foreigner. Some foreignors where proselytes and some were not. Proselyte foreigners were under the law same as Israel and were forbidden to eat dead animals same as Israel. So when the scripture states to sell dead animals to foreigners it means non proselyte ones. And the ceremonial wash only applies to Israel and proselyte foreigners. The goyim were not under the law.
