Mammon is definitely an obtuse one since he’s very clearly an antagonist, but he does still indulges in Greed through legal and legitimate (if dodgy) means.
Beezlebub encourages her followers to over-indulge, but doesn’t approve when it’s being done as a coping mechanism.
Asmodeus, despite being all about lust, puts a surprising amount of focus on consent.
And Lucifer encourages pride, but he takes offense whenever someone gets a bit too uppity and arrogant for their station.
I almost wonder if this is intentional, particularly towards Hazbin’s premise of “demons aren’t irredeemable”.
