I wonder how long it's going to take before they stop underestimating Pains. I guess having been a torturer for so long Ibuki couldn't help but try to get information out of Pain, but if he had just considered it for another moment, he would have realised such a luxury is unlikely.

Instead of playing around, they should fully concentrate on trying to deliver killing blows. With so much of the village and their own forces in ruins, they aren't really in any position to try to take prisoners.
