I don’t think Satan will be a villain since Bee said that he’s more of a brother figure to her, but he’s also not gonna be a hero since he’s well, “Wrath”. I think he’s scolding Mammon being a disgrace since Mam is a greedy jerk who tried to embarrass Ozzie and Fizz.
It could be a possibility, unless Satan has some reservations about Sins and lower demons being in a relationship ... or maybe it's more related to Ozzie being an hypocrite about his image ...
Personally I feel like during the big court scene, where the sins will be present, mammon tries to sent assassins after fizz, the other sins find out and the sins get mad, Satan calls mammon a disgrace. Either that or he’s just calling either stolas or asmodeus a disgrace.
So, if you think about it, if Lucifer and Satan are brothers, then Charlie and Damien are cousins, and Satan is Charlie's uncle, then Narissa Satan's wife and Damien's mother is her aunt.
I see Lucifer as a figure head while is Satan as the prime minister of Hell that deals with the bureaucracy keeping everyone and everything in line which is why he’s so buff cause he’s figuratively holding Hell on his back.
I think Satan is more like an enforcer who keeps the hellborn demons in check. He could be second to Lucifer since his ring of Wrath is the second one after Lucifer's ring of Pride.
I can kind of see Satan being both an Ally and an antagonist but still being a good guy cayse from what beelzabub thinks good of him like a brother so maybe he's one of the nicer sins which is ironic cause he'd satan and the sin if wrath
In my opinion his character position is kinda similar like to character from South Park: Satan - a major anti-hero and anti-villain character in Hellaverse franchise, serving as a former major antagonist turned supporting character in Helluva boss and a anti-heroic major supporting character in Hazbin Hotel. Type of Villain - Satanic Wrathful Monarch. Type of Hero - Parental Dark Lord. I also think he can be given the traits of Nergal from the animated series The Grim Adventures of Billy and Mandy, and Satan from the short film Son of 666 and the comics Zoophobia. He is going to married an earthly woman and had a son, Damian the Anti-Christ, like Nergal made it with Sis and had a son Nergal Jr., who would be Lucifer's nephew and Charlie's cousin. Well, the plot and the conflict with him will revolve around the fact that Damian will possess great incredible power, such that he is capable of plunging the world into chaos and destroying humanity, and most of all he will be forced to do this by Roo is the root of all evil, and then yes Damian, like Oliver Grayson from the Invincible comics, will confront his cousin and uncle and father and mother and other characters trying to stop him. But in the end, Damian will stop himself, realizing what he has done, and go against Roo, which has already managed to summon its army of monsters - the Beasts of the Apocalypse, and its supporters the Horsemen. The role of the Whore of Babylon will be taken over by Roo herself.
