It does raise the question as to why "Jealousy" isn't a deadly sin?
Envy has so much in common with othe DS's, such as Gluttony, Lust and, especially, Covetousness that one feels that jealousy could quite well have been fitted in - make it up to the Nine Deadly Sins, why not?
If we were to do that, what would be the Ninth?

(The others are Pride, Anger and Sloth, to save you-all having to LIU - please don't ask how it is I know them all so well!)

Given current context, how about verbosity?
