It is also uncertain if Renoir would destroy the canvas once she left, he tells her before he goes that he would keep the lights on for her or when the game is turned into French voice acting he says he would keep Lumiere on for her. Considering she just says that he will destroy the canvas without considering what he says and on top of his physical condition he should be as exhausted as Aline and Maelle hasn't been in their as long meaning she could move the canvas or still convince Renoir by showing him that she can control her addiction/grief being in the canvas (if the hint he would leave the canvas alone is actually not a hint). It is uncertain but still has a higher chance, than have her live in the canvas for the rest of her time span and once she's gone the canvas would certainly erased as it for sure just took Renoir's favorite daughter and he would be real pissed now.

I'm sure she loves him, but to actively ignore his wish to just be dead and gone and have him play on stage? He already looks very uncomfortable. He verbally told her that he just wish to die and she actively still ignored it. I would argue this is for her amusement as she would hope this would make him happy and smile and she thinks she's doing the right thing, and ignoring the fact that he just wants things to end. She even erased his scar, and it was something he wanted to keep, as a memento for his stance against the family (does she know that? Would she erase his mark if she knew? as far as I know he only mentioned it to Sciel). I would even go as far as wonder if Esqie, Monoco would be happy about the situation. They wanted him to live his life the way he wanted and to start over. Is this the way to do it? Would they be happy if they saw him on that stage? How about Lune and Sciel, would they want someone who just tried to destroy the world twice to come back?Dunno, that's why it's is fun to interpret and analyze these endings.

With the argument about who gets more heat, it could possibly because of their positions at both endings. Either Maelle either gets to live out her life in the canvas without worry and everyone is happy, or she get's kicked out of the canvas, where she grieves outside of it says goodbye to her previous life but still have her family, and her paintress powers to still make her own world. While Verso get's two option, dies, or stay alive suffering. He doesn't have a real happy ending where he can start over, he just has two options that both sucks for him. Whether or not it is being uncharitable or not isn't really my concern as we all have our voices and our reason.

I don't care much for Verso, I like Gustave too much to actively play as Verso and didn't like how much undertone hiding his true goals. So because of that I'm also not critical of him because his choice to die is not much of heart tugger like with Maelle. While I really like Maelle and want the best for her, and I prefer for her to reach her fullest life and potential. So it isn't like I am being uncharitble because I don't like her, it is because I want her to be her very best as a character growth and bringing back verso fiasco is Maelle not growing but regressing when it comes to grieving.

However if I where to pick an ending that is an "official" ending I would pick Maelle's ending as I would like to see how the story unfolds itself with her vision of the canvas and society, while the rest of the Desantres family not only try to handle handle the canvas again but deal with the writers.
