"Bigger picture? Do you really think that will change things? I can fight them just fine. The more I have studied my ancient bloodline, the more I have grown. We are stronger than ever." Scylla had listened to everything that Su had to say.
While Su had just bumped in to Scylla, it was not surprising that Scylla had wanted to know everything. However, Scylla as a general was wise. She was able to do a great deal of organization and strategy.
As a person, Scylla was blunt as they came. She was a clear cut example of what it meant to be a demi-human. She followed the battle forward side of their society very clearly. She also stood for their traditions very often.
This being the case, she did not care much that there was a way to look at a bigger picture and alter the system she had. As the holder of a unique ancient bloodline and the Scylla's inheritor, she was just the inheritor of the blood.
Creation is hard, cheer me up!
