I have a theory that maybe the senju, well maybe not all of them, are actually planning to used the uchiha all along..Why do I think about that?? Because of two things :
1. konoha located in the fire country.. we know that the uchiha has an affinity of fire element… and like we see often, the element affinity of shinobi who lives in other country have a close relation with his/her country.. zabuza, kisame, suigetsu used water.. and they come from the mist village who located in the water country, those rock village in kakashi gaiden used many rock/earth element and also deidara used earth element… and so on.
I kind of think that maybe back then.. the place where now known as konoha are where the uchiha lives so maybe the senju wanted that place to became their place? Cause I think I remember that the fire country are the biggest country of them all..
2. The kyuubi… ok.. I’m really wonder why do danzou and the elders (who all of them have a big possibility are a senju) seems to want to protect the weapon so bad.. and I don’t think he want to protect it to prevent akatsuki to reach their goal, even it seems that danzou doesn’t care about akatsuki.
it seems that other than naruto.. there is no one who ever be the kyuubi jinchuuriki.. but in other hand… the kyuubi seems are owned by the uchiha.. at least they are closely related. And I think the kyuubi are the strongest bijuu of them all, so maybe the senju have some importance for having the kyuubi??
So with those two things I kind of think that maybe that’s why the senju wanted the uchiha to be their alliance… and finally after konoha acquire the kyuubi and sealed the kyuubi inside naruto… that is the time for the uchiha to be wiped out… cause the uchiha doesn’t have any use for them now..
Can it be true??
