There is one missing Latin word in the above set of 13 nouns.
Add it and partition the full set into two ordered sets of seven - so that to each word in G-set corresponds a matching word in B-set.

Add a short comment describing the final output.

I agree.

Wiki also gives 'Humanitas', kindness, as the opposite of Invidia.

Whether there are 7 virtues, or 4 or 8 seems to depend on the source.
