Porn. Obsession.
They think malfoid was created for porn, which makes them a hypocrite to strawb. They are a leech thats upset someone else stepped on territory they invaded themselves.
How does 5:5 prove works are needed? It just proves that no sinner who embraces sin will enter heaven.
Also 2:8-9 does literally say through grace and faith, the gift of god, not works, "so that no one may boast".
Its technically not part of their religion, as its never mentioned in their book, its a random idol that they assume their prophet like pissed on or something, which is why they lick it like animals.
Therefore, its not a warcrime to destroy it.
