I suggest you accept that a parable is a parable and not worthy of building a doctrine upon with one other Scripture aimed at the eternal fate of demons/fallen angels. I further suggest you read the Scriptures for yourself and see how many proclaim, right from the very first book, that the wages of sin is death. Nowhere does God tell anyone that He is going to torture and torment forever those who reject Him in the final analysis. There are also many many Scriptures that proclaim God to be loving, just, and merciful. Perhaps you prefer a sadistic God. Plenty seem to.
