The first thing she coherently thinks, when she's thinking coherently again, is that... clearly this attack was dungeon sponsored. The timing was also very suspect; if she were an ordinary dungeon, she suspects this is when her village would be at its weakest. One of their best fighters would be distracted babysitting the dungeon, but they wouldn't have gotten any magical items out of that dungeon yet. And then instead, because she's amazing and brilliant and not at all an ordinary dungeon, all of the people that were sent to capture unwilling slaves are dead. Well, probably. Granted, some of them might still be alive, purely at the discretion of her humans, but either way, it would be extremely not what an enemy dungeon would have been expecting.
She attempts to figure out if she has some kind of emotion about the killing of people, all of which were almost certainly leveraged victims of an enemy dungeon, but mostly what's coming back is cold tactical assessments. She should probably see about assassinating the dungeon responsible sooner rather than later. She hopes that someone of the attack force is alive, not really for the sake of the preservation of life, but because she wants intelligence on the enemy dungeon. Furthermore, she is absolutely certain that the dungeon responsible is in fact her enemy, because, uh, sending what's essentially a slave army to capture shiny new slaves for dungeon power definitely isn't any friend of hers. She doesn't want to negotiate, she doesn't want to teach the poor sad dungeon how to love people, she doesn't want to attempt to navigate the likely delicate dungeon geopolitics at play, she wants a person that has almost certainly made quite a lot of other people suffer dead. Is it maybe a bit messed up to handle killing people by wanting to kill more people? Maybe, but she never said she wasn't, so. Probably she should wait to indulge her murderous tendencies for if her guess about their gear turns out to be correct or not.
... It does kind of hurt, that the humans she killed were almost certainly victims. Victims who were choosing to make other people suffer to presumably lessen their own suffering, but still. She pities them. It sucks that they're dead. But she doesn't regret her choices. ... Okay, while she doesn't regret killing them, she kind of regrets not having prepared better. But if wishes were fishes, no one would starve, or something. If there are more detailed feelings, they'll have to be shaken out over time. For now, this seems to be all she's got. Or, well, at least all she's cared to figure out before boredom and being antsy about the situation get to her.
"Hey, Kose. How are things going?" she asks, when she feels like she should engage with the world again.
