[Dimturiel]

Abot Denethor not riding to battle, I think that he does it because of some kind of arrogance and of a terrible lust for ruling which he still feels in spite of the darkness that assails his city. And he tells Pippin that Sauron will not come to battle save only to triumph over him. And not only does he consider Sauron wise for doing that, but he also admits that this is the reason why he does not go to battle. Has lust for power made him so mad that he wants to be simillar to Sauron? Despite the fact that he is still able to fight, he chooses not to and sends not only his armies to death, but also his sons, just as any heartless tyrant would do. I think that this shows also how different Denethor is from Aragorn, who goes where battle is greater, together with his people.
