Well, she has already met other boys in a similar situation (the twins) and our princess has been Chaotic Good so far, every now and then we also get a glimpse of how she won over so many people (showing compassion and mercy, even after being hurt)~She has time to give those teenagers who just so happen not to be wearing helmets or uniform a speech and set them straight
lol, so extra.
I suppose the child soldiers could assassinate Carl or plot a mutiny with grave risk to their family in the likely case of failure at any point. Still, it's unreasonable to expect the same solidarity in the story to manifest to scale from a ragtag bunch of boys much younger than the story group and more prone to treacherous behaviour due to immediate motivations such as the coveted promotion. Also, why is the weak strong conflict necessarily bad? It can ensure that good forces rule just as it does bad. Case in point, the abolition of slavery in the US.Should have killed them anyway, they started shit out of fear of a dead guy.
Their family was enough motivation to kill harmless people but not enough to stand up to some bitchy officer. Strong against the weak, weak against the strong, they just make the world worse by living.
