What if the spirit demons are the seven deadly sins?

Well, now that the darkins much represent the 4 horsemen of the apocalypse, it clearly debunked the seven deadly sins theory on darkins. So my theory is that what if the demons in runatera represents the seven deadly sins like:

- he feeds on the darkness. he likes to bring nightmares to people because he's eager to do it. So why not give him the sin of GREED. (mostly active around the runatera specially demacia and the dream world)

- he likes to eat ( i dont have that much to say because his lore thingy) so why not give him the sin of GLUTTONY. (mostly active around the runatera specially bilgewater and the river/watery places)

- he like to kill because it brings him fun like a psychopkiller so why not give him the sin of WRATH. (mostly active around the runatera specially noxus/noxus cities)

- more i like it or not, i always thought fiddle would be retcon as a shadow isles character because the mist can make you alive thingy which fits fiddle more lore wise and he wants to promote fear but if they intend to make him a demon spirit then i would suggest give him the sin ENVY because as i can see. he wants to bring fear because he envy humans. sorry i just had to bring that up because i don't know hat to say about fiddle. (mostly active around the runatera specially ionia(because it has so many farm fields)?? or farm fields)

- if evelyn can be a demon spirit other than a shadow isles character. why not give him the sin of LUST but i wish there would be another seducing woman besides eve(plz rito). (mostly active around the runatera specially shadow isles)

- if he will be retcon as a demon spirit. why not give him the sin pride because he likes to PRIDE a lot lol. (mostly active around the runatera specially freljord)

this leaves the sin sloth which a new champ demon that resembles this sin would be a great addition to lol. and a great way to be a herald of the demon spirit race.
