this is good thread....kabuto thought himself he was badass...he just wanted to be in that league of badasses villains..but at the ended he ended up being used By orochimaru ,Tobi and Madara....
1st- it was in truth oro who got madara's dna and was gonna revive him
2-Kabuto thought he was blackmailing Tobi but thats not true it was tobi who used him ..
3-kabuto dumbass who thought madara was his edo-pawn..he underestimated madara..but it seems as if madara knows lot of stuffs about edotensei...what kabuto didn't know is that madara knows the seal how to stop edotesnei YOU STUPID KABUTO !!!....
4- YOU STUPID KABUTO : YOUR BIGGEST MISTAKE WAS SUMMONING ITACHI UCHIHA...YOU SHOULDVE NEVER REVIVED HIM...ONCE AGAIN THE UCHIHA SEEM TO BE THE TRAUMA FOR BOTH KABUTO AND ORO...OHH ITS CLEAR..THE GENJUTSU CAN TAME SNAKES LIKE PETS AND SHARM THEM ..
5-..KABUTO FOR OROCHIMARU IS LIKE OBITO FOR MADARA...HE WAS USED LIKE PAWN BY HIS MASTER...
Well first, he could destroy Madara's personality and assume complete control at any point, so there's that.
Second, it's entirely possible he knew Madara could break out and that it was a backup plan for Kabuto in case he's incapacitated. Look at what he tells Itachi. "If you're too impatient you might be unable to stop things that could be stopped... And cause the opposite to happen." Then it cuts straight to Edo Madara.
kabuto saw that coming. first thing he said to madara was "im your ally, dude, im on obitos team so no hard feelings". so madara wont betray him just to be evil.
and if madara tried to break out whats to stop kabuto from killing his personality? and madara was controlled when kabuto first summoned him on obito
