''my girl died so i'm gonna make the whole world pay for it'' ..umm, I'm gonna go with Sasuke.
For sasuke it was "my big bro died for konoha, ima destroy konoha"
OBITO hans down it seems every uchiha has an aveger conflict
For sasuke it was "my big bro died for konoha, ima destroy konoha"
Uchiha Obito, simply because he is more of a badass than sasuke currently, and the bloodbath of those ninja he did with so little experience and using MS for the very first time. WOW!
obito of course, rin's death was the trigger to unleash obito, he wanted to punish minato for not being there to prevent rin's death (the konoha attack), and he will stop at nothing until he either succeed in his plan or die. Now sasuke have always been manipulated and didn't know whats what i mean its silly that at some point he didn't even know why he's angry and still wants revenge.
Obito is the character who fooled the entire shinobi world, sasuke just fooled himself
