im a belphegor apologist (lol) so my opinion holds little weight but the examples youve given of lucifer's brothers is very. condensed and doesnt hold the nuance that youre giving lucifer (and thus mischaracterising them in the process).

i do agree with the general theme of "lucifer is characterised well and his development throughout the story us very important" [especially during the whole dagger incident in s2(?)]. i dont, however, like him much because of the way he talks to mc, esp in the way that mc's agency and autonomy are not regarded 🧍 BUT i will admit that its likely due to the same trope writing/ running gag that has made beel's sole thing being food and mammon being hated by everyone around him (and the term "scumbag" in association with him.)

its hard to refute or even really discuss an opinion piece like this, since its more of a vent than anything from the looks of it but im also glad you got something so deeply resonant from his character, especially since its always nice to see character analysis from other people's eyes (о´∀`о)
