He also doesn't give a shit about, Naruto. He didn't even give a shit about the supposed God of the Narutoworld arriving or his entire life's ambition supposedly falling apart. Besides, it's not as if Sasuke cares about him, so I guess Madara is just as pathetic going by your logic. He is supposedly the greatest Uchiha, and for someone so loyal to his clan not to care, he must really be pathetic.
