I agree, this could certainly be one of the motivations for Ymir's decision to go with Reiner and Bertolt.

I always thought that Ymir wasn't telling the truth when she told Reiner and Bertolt that the reason she was going with them is because she wanted to "repay" them for returning her to her human form. Not only because it meant leaving Krista, the love of her life, behind, but also because it goes against everything she stood for.

She was telling Krista, literally hours before, to live her life for "no one but yourself", and now she suddenly decides to help Reiner and Bertolt out of the goodness of her heart? No, she definitely has some other agenda in mind in deciding to go with them.
