According to history, Date not only survived all the bullshit that went down, but he managed to schmooze both Hideyoshi and Ieyasu - even after basically giving both of them the finger on seperate occasions - and was awarded the Sendai province, which became incredibly successful mostly because he was open to trade from the West despite nominally supporting Ieyasu's ban on Christian practice. He wrote a letter to the pope and sent a fairly large delegation to the Vatican in the interest of setting up trade, and he basically trolled everyone, ever, hard. He was notorious for his reckless approach to battle, as well, but successful despite it.
Also, he either cut out his own eye or had a servant do it for him with a knife because it was hopelessly infected. At like, age 7.
And he wasn't even supposed to inherit the clan. His mother favored another brother on account of that brother had two eyes, but Masamune wasn't going to put up with that shit.
