For everyone else who wonder the same question and didn't get the answer during their playthrough : Malady, sometime in the past, made a deal with some very bad and powerful entity and now she wants out of it, so in Divinity : Original Sin 2 she tries to find someone capable who can help her to break the deal or at least protect her from consequences. She believes that protagonist (the player) has potential to become this person, especially if will become a Divine. So basicaly her goal is to set the player on this path.
What conditions of the deal? We don't know yet. With whom Malady made it? Someone or something even more powerfull than Adramahlikh, if even he/she/it couldn't or wouldn't break the deal. Personaly I think that candidacy of Damian is too much red herring and so far-fetched, but Larian probably will go with it. Maybe arch-demon Asmodheus would fit on this role and also will connect some dots with BD, but I don't think that Larian would choose this variant. Only Tree of Insight knows.
