My point is that "he didn't want her to suffer" is not enough justification for some outlandish feat that was never mentioned in any other form of media despite ample opportunity for it.

He could have taken out Obito. Didn't though. Even though he thought it was Madara, the war-mongering Uchiha who discredits the Uchiha name.
