Again my friend Howdy brings some interesting thoughts which i would like to share with you guys.
Alot of people are disappointed after seeing Nagato. They seem to lose hope that he is final villain. For one thing, do you believe madara is final villain? Its too late for that. Pain has done far more damage to naruto (the protagonist of this series) than anyone else. He killed naruto's sensei's, he destroyed naruto's village, he just did more damage than madara has done. What do we know about madara?
He was a sore loser who did not win title of hokage position, and then he complained and even his own family members found him annoying and didnt like him. Thats sad. He left the village and striked back with revenge, having the king of bijuu's by his side and the highest level of sharingan known, and still got his ass kicked. He then waited until shodaime died to strike back again and his plan got foiled yet again. He failed so many times he wears a mask now.
This guy is pathetic. Itachi even said it. All we saw madara currently do, is run away, and fail even more. He said he could vouche for sasuke. What happened? Sasuke failed. He brought back a tentacle and everyone in akatsuki laughed their asses off while madara was embaressed yet again. This old fart is a joke. I cant believe there are people who believe madara is worthy of final villain.
Nagato accomplished more pinned on a machine than madara having hundreds of years along with a space time jutsu. Madara is just made up of so much fail.
Anyways, back to Nagato. People say hes pathetic because hes crippled and not fighting on his own.
Is Madara able to fight on his own? Then why does he rely on akatsuki for completing his own goals? Why does he try to keep his identity a secret and not fight the main characters? Is he a cripple?
Is Itachi not able to fight on his own? If so, then why did he choose to shorten his own life and weaken his vision by relying on the harmful techs of mangekyou sharingan? Is Itachi a cripple?
Is Sasori unable to fight on his own? Then why does he take time to work on puppets and have them fight his battles? Is Sasori a cripple?
Is Naruto/Killerbee/any other jinchurikii incapable of fighting on their own? Then why do they waste countless years to learn to control the bijuu within? Are jinchurikii's crippled?
So by your logic, if Nagato is crippled, so is half the shinobi's in this manga. As far as i know, Nagato is on that "machine" for as long as Pain has been in effect. Theres no reason to believe Nagato is crippled. Just because we havent seen his legs doesnt mean anything. He could be on that machine because it probably helps him put pain in effect.
So just think about the statements above. You will either contradict yourself, or understand the truth.
