Naruto Thread (Spoilers For Sure)

I disagree with people who say these flashbacks are useless. It's nice knowing the story of kabuto and all, since we get to see that he's not just evil to be evil.

Another interesting fact is that Orochimaru used to be in root.

Both are useless because:

Orochimaru is dead and doesn't need any more development.
Kabuto will most likely soon die and doesn't need any more development.

It's the same when they showed flashbacks for Kisame. Most useless flashbacks ever. Not only did they fail to make Kisame more likeable, nothing really substantial came out of it.
