Adam already exists in a weird fluctuating state between "incompetent" and "getting-shit-done mode".
>lets his Exorcists leave countless weapons just laying around in Hell
>but then immediately launches an investigation and moves the Extermination up six months when one of his girls gets killed
>accidentally confesses to the Exterminations in a public trial
>but then immediately moves to silence any Hell witnesses (i.e. Charlie and the Hazbins)
>dominates most of the fights he's in, only letting Alastor flail around for a little bit just for funsies
>his last retard moment is trying to take Lucifer head-on (though you could argue that he is rightfully outraged by the Duck-Fucker making light of all the ways he's fucked Adam's life up, and therefore cannot think straight)
Sera, in comparison, does NOT have any flashes of competence whatsoever:
>has a magic orb that lets her straight up spy on all of Hell at all times
>claims that the Exterminations are done to prevent uprisings, but does NOTHING to check if Lucifuck and co. are actually planning one
>runs an autistic campaign to keep the Exterminations secret, even from her ostensible superiors in the Archangel Council, because ??????
>does NOTHING to stop Adam from blabbing during the trial
>does NOTHING to stop Adam from bumrushing the Hotel
>does NOTHING to assist or save Adam when Lucifag and SHITffty are about to kill him
>will evidently do NOTHING to avenge Adam in Season 2, leaving the responsibility to Punished Lute
That last point on Adam’s section is still bananas to me. Like, say you make the devil actually misguided. He’s still the literal root of everything that has ever gone wrong for mankind because his plan backfired stupendously. But, no, we can’t even call him that thanks to his speech. He’s bragging about the Story of Adam and Eve. Eve, Adam’s wife, who was tricked into eating the Apple by this asshole. Like if anything that entire scene would have been duck fucker’s villain reveal or his villain speech about how he’s ruined a man’s home, and then, likely, did something unspeakable to his wife, ruined all creation essentially, and is living his best life, happy about it.
(Props to Viv if in season 2, it’s revealed that his sad boy persona is just an act, and his main method of fooling people. After all, can this short sad guy really be unconscionably evil? Even bigger props if he’s using Charlie as a Manchurian candidate to send to earth with her shitty redemption ideas, specifically because they will not work and even end up damning more people than they’d otherwise save. It won’t happen because Viv‘s entire world view hinges on a relativistic morality, so Good and Evil cannot actually exist, meaning Hell and Heaven have no purpose and cannot exist in that framework, but still.)
Sera is what happens when you want God, but and this is me speculating here, don’t want to actually blaspheme against the Holy Spirit. Besides, if she’s the leader and Heaven is bad because they sometimes have standards about how you should act, you can’t have her say something understandable like: “We’re doing exterminations as a precaution because we trusted that asshole we threw into Hell once, and look were it got us, humans, and Adam especially. He has made nothing better and has only caused issues for creation as a whole. Plus, we don’t decide who goes to Hell apparently, so there’s a 3rd party making that choice, meaning that sinners are there for a reason. I say let’s put them out of their misery as a mercy. No Emily, you’re wide-eyed idealism is stupid and akin to a human child or a Marxist. Please sit down and shut the fuck up before your Mother/Sister has to smack a stupid bitch.”
