Obito is the one who attacked a mother giving birth,trying to kill a newborn baby,rip out a bijju from a helpless weakened mother's body,not to mention that mother was his own sensei's wife and a baby.
Obito Attempts to kill a baby by blowing it up with an explosive tag
Obito unleashed Fox on village making him directly responsible for everyone that died then.
Thanks to Obito Minato and Kushina died and Naruto had to grow up alone as a Jinchuuriki hated by the Village.
Obito helped to kill his own clan, Obito also played with Sasuke telling him the truth.
Attempted to destroy all the world, directly responsible for starting a war making him responsible for 10,000 deaths, helped form and corrupted a missing-nin group and captured all the jinchuurikis. Revived the Juubi and Killed more of ten thousands people when became Juubi's Jinchuuriki.
5 minutes of his 'redemption' isn't making up for a lifetime of deaths and crimes. Just because obito had a change of heart after all his plans went to shit and he learned that madara killed Rin and planned it out from the get go means nothing.
Naruto:
"Hey, that guy that brutally my parents, hundreds of my fellow villagers, Tried to manipulate my "best friend" Sasuke, created the Akatsuki to hunt and Kill Jinchuurikins like me, started a war and killed thousands of people.
Buy Hey he had the same dream to become Hokage I did.
Isn't he the coolest?"
Naruto comes face to face with Obito, the guy who literally ruined his life and also sasuke's life and caused everything negative to happen in the entire world and he's just like "oh, it's never too late, you can change, we'll forgive you, you can be hokage."
No human is sane enough to forgive and still defend a mass murderer who caused global atrocities, and started a freaking war only because he wanted to be Hokage when he had 12
I wanted Naruto to display some form of realism, but then when he pardoned Obito and still defended him ruined what little good will a had left for Naruto....
Black zetsu only said the truth about Obito.
Naruto didn't have to defend him against BZ.
What he said was COMPLETELY UNREALISTIC and he lost many fans after that BS statement.
I liked Naruto when he was more goofy-ish and fun. Then in the war his personality and character type just completely changed to this "wanna-be" righteous hero...
