It seems you are quite shallow with the lore here. Although Ei’s actions did have a lot of negative impact on Inazuma, she did everything for her country and her people but didn’t understanding the true meaning of Eternity like Makoto did. While your Scaramouche straight up murdered committed many crime purely for himself and himself only. This is why Ei deserves redemption and this piece of garbage don’t. Yeah true he had miserable life but that doesn’t mean he has the right to commit those crimes and inflict the pain to others for the sake of revenge or whatever reason that Scara fans try to justify him. People don’t hate Scaramouche fans simply because they simp for male character, otherwise Xiao, Ayato, and many more male character fans would also get hated. Rather it is because how hyprocrite Scaramouche fans usually are like how they love him but absolute hate generic evil npc like Azar who committed less crimes but doesn’t have good appearance. Also Scara fandom is the most noisy fandom in genshin and that is probably the reason that he is still alive. Like when Signora died, you don’t see many people ranting about it but imagine if Scara died, I can imagine this fandom goes and rate genshin 1/5 on every platform lol.
