How dare this guy come up with a comment like Jiraya is not strong... You need to watch his fight again Pain on Youtube:

Please tell me who else could do this much to Pain without know his powers. Not even Kakashi could nor the rest of the Villagers including Tsunade. Pls refrain from saying such things if you haven't analysed your hypothesis or theory properly.
Btw if he was alive, I doubt that he would have done much... he might have fought Madara with the Kages and died honourably or used TNJ on pain in the battle to turn him around to fight Madara and Obito
