Ok, since you refuse to understand my point, let's try a new tactic.
In Erfworld, the only units with true free will are rulers. All others units, by their very nature, are obligated to largely agree with their ruler. Bea had the option to fight, lose, croak and be decrypted or submit to GK's rule as a subservient vassal state. Those options were not palatable to her, so she chose to disband. By the very nature of how erf units are subjects of their ruler, they probably all would agree with her decision.
