So I've been on this forum for a while as a guest and I've read that apparently tobirama killed madaras brother and then Ive heard that madara ?illed his brother for his ms so I just wanna know what's going on with that
Tobirama critically injured Izuna. In order to help Madara protect his clan, Izuna offered his Eyes to Madara. This is also the reason why Madara took revenge on Tobirama by impaling him with Black Rods.
