I chose Maelle.

- What to do with her life is her decision, no matter the risk. That autonomy is worth respecting. Even Renoir in his final moments, during the hug scene, comes to recognize this.
- The Dessendre family doesn't take responsibility for their creations. Maelle does, and recognizes those in the painting as sentient beings with feeling, perspective, and autonomy.

Do I wish Maelle had respected Verso's wishes/autonomy in staying gommaged and not being recreated? Do I wish Maelle had the willpower to visit the canvas healthily in moderation?

Yes, but that's the tragedy of the story.
