I think its kinda tragic though seeing obito the way he is now. I mean he was like the ultimate tragic hero when died, changed kakashi's way of life completely and yet here he stands now as the ultimate villian. Though wanting to control the entire world cause of a broken love is extreme, i wouldnt belittle it either, especially if his last 'living' thoughts was about how he never had the chance to confess to her...that could fuel some power shit man
