Preferences
Mithrandir had asked me, why would I desire to side with the Dark Lord Sauron? Had I no faith in our own strength anymore? Did the fool ever think that perhaps I was wise enough not to follow my preferences, but my common sense? There can be no coming out of this great battle alive unless one sides with the greater power – and in this case, that power is Sauron. Mithrandir may think that he is strong, but he is weak. Even after we spoke, he could not see reason, he would not join me in swearing allegiance to the lord of Mordor.
Against my preferences, I have sided with the Dark Lord. But in complete agreement with my preferences, I have turned against that fool, Gandalf the Grey.
