I appreciate a fellow snek lover, but I will speak up in Naya's defense. I think she does try, when playing her route she actually isn't eager for war, she just feels she can't contribute to being a guardian and matriarch except through violence. She also is *far* from the likes of Kendra, as can be seen when she approaches a caravan of neutral town citizens migrating, they don't seem terrified of her, implying that she doesn't just go around killing random innocents for fun, without at least the genuine belief that they're raiders or bandits.Key difference is that Diula tries to be a good person. Unlike the foolish cat.
While she does treat the MC to a very spartan training regimen, it's genuinely for his safety, as he's always at risk of being kidnapped and raped (to death) in Lycolis.
I wouldn't say she's super moral, but she's leagues above the likes of Kendra, Nyxmay, and Yakuu. I'd put her at a solid Neutral to the former's Evil.
