Why don't the senju steal sharingans

[The Hidden Shinobi]

1) They are not power hungry scum

2) If they were already stronger then the uchiha and the strongest clan why would they need it? Pretty worthless to them

 

[supino]

it's not their way of doing things; they did not believe power is sth tangible: a sharingan or probably not any jutsu, hence nobody tried to steal Hashirama's mokuton either. they believed power was the ability to be in a team and protect your friends which comes before all else. hence, the will of fire is their legacy. whereas the Uchihas if they leave a legacy behind that's usually a pair of eyes. the two clans just understood the concept of power in different ways.

bcuz they are senjus - they dont need it
