No, re-read the chapter, Tobirama says the Senju believed in that their power was associated with love. where Uchiha believed in the opposite. However, Uchiha clan treasured love the most and with this, they could awaken something stronger than the Senju's power of love. indicating the Uchiha had more potential than the Senju.1- tobirama wasn't talking about power, only love... And how that love becomes hate, hence the evil curse.... It's inevitable
Again, re-read the chapter. Orochimaru said to Tobirama that Madara seems to be his trauma, whereas Tobirama replies with "you don't know madara" Indicating fear. If two of the strongest characters in Narutoverse fear another madara coming, it's safe to say madara also is one of the strongest characters. Trauma - Is when emotional shock following a stressful event or a physical injury, which may be associated with physical shock2- I wouldn't say scared, more like frustrated.... He wouldn't listen to their ideals and resolve
Both Hokages don't want another madara to show, whereas 'a new madara' maybe standing right in front of them xD
Yeah it can go both way looking at the chapter again. eh who knows3- Sasuke just said he wasn't "pure" as in he isn't good.... Or maybe you're right, that he isn't bound to that uchiha "curse"?
