I guess under wrath you could list hatred aswell, same with variance ( had to look up what it meant in this instance) strife, murder. Well basicly anything angry..
revellings could be pride, to revel in your own grandness or accomplishment. Or with a little more stretch gluttony, indulgence aswell. When you enjoy your food so much.
I guess greed can turn a person ugly on the inside and gluttony on the outside. (I feel like a sidenote is needed... a little extra weight doesnt necessarily make a person ugly, in many cases it makes them look better. But the outside is just a package it is not what counts. But in the case of this sin excessiveness is key and it is often depicted as morbidly obese characters)
Envy instills a rage and hate and can turn people into monsters (of the human kind, nothing supernatural). Imo the worst of the group, and one that really does not have a neutral or positive side to it. It is the only one that feels truly evil instead of just unfavored behaviour.
