So whoever clung to Tobirama's laughable political propaganda was peace-loving, but whoever decided to be a part of their clan and support it were murderers and loopy? I am pretty sure the latter is an ethnically, ethically, culturally, and morally sound option, so only Sasuke, Madara, Izuna, Fugaku etc.
Obito, Shisui, Kagami and Itachi were traitors to their clans and thus deserve no praise. Whoever wanted to maintain the peace within their own people are they truly deserving of this attribute. Itachi and his Nationalism loving, loopy Co belong in Tobirama's dog house. And Obito is just a loon for sacrificing a clan just for Sasuke's eyes.
