THEORY:Why did Obito lose fight against kakashi

[HashiramaIsBack]

Listen up,we all thought that he would be final boss and Madara sealed away.I think that Obito became good deep inside him and let Kakashi stab him with kunai.And its impossible that he's rinnegan is for good look,and i also think that Obito was exhausted with all summoning and spaming kamui and that's why defeating him was an easier then it would with full stamina.The End.

i prefer saying it was plot no justu but whatever floats your boat

Well he could've stabbed kakakshi fatally but just got him by his right side which isn't deadly. He might be realizing his motivation is pointless.
