"Become the Heavenly Demon. Only then will you and I survive. You must become the Heavenly Demon. You must...!"
Only the strong survive, and only the strong can protect what is theirs. The weak are ruled by the strong, serve them, and even if they die by the hands of the strong, they have no right to feel wronged. Their death is not because of the tyranny of the powerful, but because of their own weakness.
