Well, that is to be expected to a degree. After all, the dragons were sent to capture Kilani so they could brainwash her adoptive daughter into hating her and make her more accepting of the racism that has driven the conflict of the story. That she is being brought in at all can reasonably be expected to inspire negative feelings because it represents a major victory for the antagonist that could potentially snuff out one of the beacons of hope within the story. That said, most characters - dragon and tiger alike - don't clearly fall in the role of antagonist. They're a bunch of people doing what they think is right and stuck in a cycle of hatred. Few - if any - of them deserve death.
Easy to say that major antogonist is a war! No matter how funny it sounded, but it's true.

I really hope that Kilani stop all this madness, but right now she must show some her goodness to dragons and get encouragement from someone or herself. Otherwise we see really dark story that can "broke" someone's heart just be one glance at it. Oscura also victim of propoganda of hatred. She don't even known that among tigers there is good persons. And right now i find out how big confusion and amaze Kilani may cause among dragons. Cinder already confused XD
