Halevi, ok – not divrei havai, that’s the lashon harambam; the gemara’s lashon is tiflus. Is that any better?
As for your understanding of the yerushalmi, it’s missing daatan kalos – not only is there armah, which makes them able to hide their sins, they are daatan kalos and more easily persuaded to sin than men.
