That was a beautiful tribute to a character that deserved more than he got through all of part 2 in the latest chapter. I think he should stay dead since his death's affected the battle and turned it greatly in favor of the alliance.
Bringing him back when it's all over and peace has been achieved would not taint his sacrifice, but don't revive him during the war. Let the readers think its over.
If Kishimoto chooses to keep him dead, then make sure he's honored with a proper funeral.
That's how I see it.
