Madara's asking for a bit too much imo. It was a war, his brother got killed, and now he wants hashi or tobi to die. Although I can feel him, its a bit too far asking for trust.
But in a way, i think hashirama did say no and he was wrong. Knowing madara, he isn't as evil as people think he is. It was a great chapter but can't wait for next one, wanna see what happens.
