I've always hc'ed that the Uchiha (under Tajima, for this instance) are a more family-focused clan, ie they help and protect and uplift each other and in turn, this strengthens their clan
While the Senju (under Butsuma) were very "clan first", not really caring about individual people's wants or needs, the clan must thrive no matter the cost type of deal
Which leads me to the following hc;
If this was how Butsuma treated his own kids for daring to voice their own opinions...
Then who knows how he treated anyone else who disagreed with him?
How much worse would it be if a random clan member openly opposed him? Exile? Suicide missions? Assassination?
While Madara got to know Hashirama and knew he's not the same as his father, Izuna never did. He's never talked to Hashirama as far as we've seen; barely exchanged a few words with Tobirama. So really, who can blame him for thinking they'll all end up being the same as Butsuma?
What if that's why he didn't want peace until the very end? Because in his eyes, their familial values were so wildly different that they could never reconcile? Because he didn't want Uchiha kids growing up being beaten by their fathers for developing their own personalities?
