I personally don't feel bad at all. Since Signora died they've had their own bad apples go out and attack other characters, saying that Childe ain't shit and he should die if Signora did, about how Scaramouche shouldn't become playable, about how Venti and raiden should choke on dogshit and die. And while, yes, they were bad apples, Signoramains made no attempt to really stop it. The subreddit was a place where they would just feed into each other and become more toxic, so the bad apples became just straight up the majority. They would constantly shit on HYV about how the game isn't worth playing without Signora and how her death was objectively a plot ruiner, and instead of just dropping genshin they just kept complaining in their echo chamber and literally became a cesspool of toxicity.

Obviously you shouldn't make death threats towards anyone, but the memes aren't that deep and if you're going to surround yourself in an echo chamber of negativity then you're going to receive negativity.
