I don't think the story was in any way attempting to excuse her actions; it was just displaying how the cycle of hatred keeps going round. In any case, she clearly has a flawed personality.

She just admitted that she's killed for the sake of praise. She's clearly selfish (e.g. ch.92 where she couldn't understand why Falco would protect an enemy, and assumes he's doing it for points with Magath). She's overly aggressive (her behavior with the other candidates and her obsession with "killing"). I'd also still argue she was flawed for her Marleyan beliefs, even if it was due to her environment.

Isayama was intending to blur the lines with Liberio, but the main cast (esp. Sasha) were still presented as good people - particularly as the Survey Corps were forced into action. They're not evil-doers who will get their comeuppance for daring to oppose the beloved Mary Sue like in normal cases.

This isn't to say her feats aren't ridiculous, but that's a whole other conversation.
