How much louder would people howl if their character began to act out a role wholly independent of the one they had, consciously or unconsciously, assigned to them? The only way to stay "safe" is to minimize personality.
Note that this argument in no way reflects upon actions taken, unless those actions are further evidence of definite personality and not simple reactions to the environment (such as get attacked, trounce assailant or see freaking gigantic dragon, run like hell).
