I only got patience and diligence
I think the virtues make loads more sense than the sins. Doing things in moderation, helping others, being dedicated, patient, kind, and humble. These are good qualities. I think maybe you think you look cool because of your statement? but really it has the opposite effect.
For the opposites, Most of them in itself arent as terrible as long as people are aware of themselves and the consequences of their actions and keep in mind the feelings of others. You just need to check your thoughts and your actions; is this gonna be harmfull to myself or others.
Like it is ok to want something, but to feel entitled is something different, or take things when it is not yours to take. Or to hurt others to get what you want. (I guess that covers all but sloth)
Maybe you are mainly aiming at the "don't do this too much. or that isnt good for you" the general stuff which is targeted when people glorify sinning. In which case it is usually about overindulgence.Which yes I can understand, it might not be great for your health or your discipline, but it is not bad for your soul or damaging other people (as long as it doesnt get out of hand like abusive alcoholics obviously).
Overindulgence doesnt make you a bad person, I think that is one basicly everyone does in one form or another. Wether it is too many hours behind jetpunk (while you should sleep/do homework) or sleep in or treat yourself to something you feel like you shouldnt.
(and I tried octo.. didnt get why that wasnt accepted, that is what he is called here. Didnt realise the american version has a different name ( octo sounds english enough)
