I found this edit of Alastor and Vox's backstories
with the song "Lust" by Medina (link here) and I was thinking...
I think all the sins are actually just forms of pride. For example:
Greed is "i deserve to have more than everyone else"
Jealousy: "i deserve to have what they have"
Lust is "i deserve love and devotion and physical pleasure"
Gluttony is "i deserve to indulge myself (drugs, alcohol, food, sex, etc)"
Wrath is "i deserve to be angry/ they deserve to be hurt because they hurt me"
Sloth is "i deserve rest"
(Just look at this cute pic of Belphegor from Obey Me)
However, you can flip it too. You can do the same thing with lust.
Pride is "lusting after praise and attention"
(Very much like Vox does all season)
Greed is "lusting after money"
Jealousy is "lusting over what they have"
Wrath is "lusting after violence"
Gluttony is just "lusting after drugs" and sloth is lusting after relaxation and laziness.
Every sin can be a form of another sin.
