Within the context of the story, it makes sense actually. Here's a Dude who's entire race was slain, on a random afternoon. By his Brother, sent by basically his own village, including his parents, in front of him. Then the gift of charity states that Dude has to live the early part of his life in the village, that sent his Bro, and he never even knew of the Village's past moves against his clan. Over the span of his life he went after to kill his Bro, to avenge his clan, and finds out it was all a rouse, and his Bro was basically used again like a tool to watch over they're enemies, whilst calling him one to everybody that would hear.
Now it shows maturity within Sasuke for not simply going ape after talking to Sarutobi, as if that wasn't enough, the particular way Tobirama chose to speak about Uchiha's warranted a response, therefore his eyes activated because he was beginng to truly get pissed. It would be one thing if Sasuke walked in shitting on everything that was Senju like Madara, but he simply came in with questions, and got pissed because he was getting lip after all of his circumstances. I didn't create the percieved animosity, Kishi did when he lit up his eyes for no other apparent reason.
