“Bless your heart” in the Southern US does not mean you’re amoral. The implication is that you failed at something because you are so pitiably stupid or incompetent that failure was inevitable. For example, you would not say “bless your heart” to someone who had already cheated you, but you might use it to suggest that you see through their scheme: “Bless your heart, but I’m not paying $10000 for a rusted-out Toyota.” “God love ‘em” works similarly but mostly in the third person, as in “Did you taste the [awful] food he brought? Bless his heart/God love ‘em.”
