A very small degree of hope
You forget that the entire Negamoon family dies. Emerald dies due to jealousy, Sapphire by Wiseman, and Diamond the same way.
Tomoe doesn't really reform, more like he's cleansed. But I don't remember much of that because it's been so long since I've seen it. I do agree that the Witches 5 die
As for the Dream Saga, I'm pretty sure that Zirconia dies while Nehelania goes back to wherever, since we see her again in the first 4 episodes of Stars. Uhm....I think the quartet reforms in the anime too since they did in the manga, and I think that Fish Eye was close to it. But I dunno, I just know those 3 die (I didn't get to watch much of the SuperS)
is sufficient to cause the birth of love
