Ep 9 and 10 are about Envy. It's translated as Jealousy. I don't know if that is a direct translation of the language used, but regardless, the more accurate term is Envy.
Jealousy relates to being obsessed with keeping what you have/own, from others. (Or what you believe you own, with regard to relationships)
Envy relates to being obsessed with something someone else has, that you desperately want.
Now off I go on a tangent...
Envy is one of the "7 Mortal Sins" of Christianity. I've always found this puzzling . Jealousy seems to be the opposite of generosity, a thing touted as being central to Christian morality. But envy; wanting what someone else has, is set as one of the greatest sins of all?!? Baffling.
Acting on that envy, being IMPULSIVE and murdering a child. Yep, that's a mortal sin alright but at that point, falls into a different category.
I will stop now with my philosophising.
