Rosetta is trying to relate to Maxi in her own way. She is saying that because even just by being forced to watch that he cannot trust and finds trouble loving, that it must be even worse for Maxi because Maxi actually went through the beatings. She isn't trying to rub it in Maxi's face. I'd recommend reading it again and trying to understand exactly what she is or isn't saying. I think Rosetta is best defined by her actions -- and her actions allowed Riftan to save Maxi as well as stopped a war.

Aaaaaaaggggg I don’t care that she’s also traumatized from watching , what a bitch
