??? No judgement or anything but I have no idea how you could come to this take when we had plenty of female villains in the 90's anime such as Beryl, Esmeraude and the Witches 5 who were never even given the chance of being redeemed.
There were a few male villains who got to be fully redeemed and live after too such as Ail and Dr. Tomoe. Depending on how you interpret it even the Amazon Trio were alive after their redemption as well.
In fact I would say the 90's anime is even better in this regard, as the only male villains Naoko attempted to make even slightly sympathetic were Kaitou Ace and Rubeus, and even with Ace it wasn't much because he was ultimately just a raging incel anyways.(Not sure if the Shittenou count here either since one could argue they were just brainwashed in the first place) Meanwhile while they ultimately end up getting killed in the end, Naoko did give us characters like Beryl, Black Lady (if she counts), Galaxia and the Twin Senshi Lethe & Mneosyne, so I would say you have it the other way around in terms of how the male villains are treated when it comes to the 90's anime vs the Manga.
Well, it was a tongue-in-cheek take poking fun at Nehellenia and would only apply to characters who were redeemed.
The male characters I was referring to were ones who did something worthy of redemption before they died. (Fish Eye protected Sailor Moon, Nephrite protected Naru, Saphir attempted to stop Wiseman.) Beryl, Witches 5, etc also never redeemed themselves so they would be exempt.
Tomoe was possessed and in the anime, never wanted to do those awful things.
Meanwhile, Nehellenia was awful. She didn't attempt redemption, she killed her own subjects (possibly an entire kingdom) and would have one the same to everyone on Earth, just because she wanted to stay pretty forever. She then tortured Sailor Moon and her friends when Galaxia freed her.
She would have destroyed them all.
I'm glad that she had a change of heart after she was defeated and had no choice, but I don't think she would have, otherwise.
If Chaos had been involved or if she was being controlled by Zirconia, I'd have more sympathy for her, but as far as we see, she chose her actions.
Personally, I preferred her as a straight-up bad guy, her happy ending didn't seem deserved and didn't really make sense. It was touching (Though I'm still not convinced she wasn't just trapped in her own dream).
As for the Black Moon sisters, their stories were touching, but they also never attempted to redeem themselves. They only did so after losing everything and having nowhere to go.
The same could even be said about the Quartet, in the anime, I guess.
And as I said, in the manga, if you're bad, you die, male, female, deserving redemption or not. Besides the Quartet (who there were truly victims) I don't think a single villain was spared.
So even though it was mostly a joke comment, I still think it stands that redeemed male characters had it worse than redeemed females in the anime.
The manga was pretty equal all around.
Dark Kingdom:
Beryl: never attempted to redeem herself. Died.
Jadeite: No redemption. Died
Nephrite: Redeemed himself actively, still died
Zoisite: No redemption: died
Kunzite: No redemption: died
Aliens:
Ail: redeemed, lived
En: redeemed, lived
Black Moon:
Koan: received redemption after losing, lived
Berthier: received redemption after losing, lived
Calaveras: redeemed after losing, lived
Petz: redeemed after losing, lived. I loved that the sisters found happiness, but I don't think they actively tried to be good until they had lost everything. They were petty, mean, spiteful (all traits that I'm sure they had without the earrings but were magnified) up until they lost everything. I would give them more of a pass than some because even though it seems Koan is mostly upset over that trash Rubeus, I think the separation from her family hit her the hardest.
Rubeus: never tried to be redeemed, died
Esmeraude: never tried to be redeemed, died
Saphir: redeemed, died
Demande: redeemed (sort of?) died
Black Lady: was manipulated, didn't count
Death Busters:
Kaori: never attempted, died
Eudial: never attempted, died
Mimette: never attempted, died
Other witches no one cares about: never attempted, died
Tomoe: was manipulated, didn't count
Mistress 9: never attempted, died
Dead Moon:
Zirconia: Do they count as the actual big bad?
Tiger's Eye: redeemed: died but was given a new life?
Hawk's Eye: redeemed: died but was given a new life?
Fish Eye: redeemed: died but was given a new life?
Quartet: all manipulated (probably)
Nehellenia: never attempts redemption, gets it anyway
Shadow Galactica:
Animamates: It's unclear how much of the evil they do is actually them and how much is the bracelets', since Nyanko seemed to be struggling after being hit by Sailor Moon's power.
Either way, all dead.
Galaxia: manipulated, mostly. lived
