I disagree with u. This chapter & last chapter helped use understand that they had a strong bond before they became enemies. It gave us a understanding of there skill by saying they was defeating adults at that age. It showed y they wanted to start there own village & y the location. Also u say this battle is about to be pointless but I think that Madara & his bro will unlock the MS in this fight. Hashi father or little bro will kill Madara's father & they will unlock MS & then kill Hashi father. After seeing his dad lose to a Senju, Madara will be determine to make his clan the strongest & will always have that hate for the Senju clan(note he respects Hashi but really don't like him when there adults). Also we see how Tobirama did get to connect with the Uchoha like Hashi did & Being like his father always thought of them as the enemy or the problem.
