oh please. cassie did what she had to do without losing her sanity. its not like she didnt pull her own weight when it came down to it. sh preached against violence but had moments of realizing it was sometimes needed.
That's how I felt.
In a way, all of them were hypocritical, consistently, in some way.
Like when Marco told Rachel she should've let that little boy die (in the Alligator pit at the zoo, when she got sick), yet in book 3 he morphed Gorilla to save that man from getting robbed. Or that time Jake morphed into a dog with Marco to go see some concert, yet when anyone else does it, he jumps down there throat. Tobias might be the only exception here.
Cassie felt bad about the things she had to do, but she did them anyway. Maybe her crazy ideals are what kept her sane, because she was the only one who lived, as PG as this sounds, Happily Ever After.
