Born a genius they said? No such thing. Itachi earned it all himself.
OP KG? Itachi mastered 3T at age 8 which is something he worked hard for. He graduated at age 7 from the academy which is something he worked for. Not to mention Itachi hardly spammed his MS. He could have acheived the EMS and the Rinnegan if he wanted - but no, he died for the sake of his brother.
Btw, your part about his plan failing is irrelevant because in the latest chapter(s) Sasuke was beginning to question who he is as a person. Who he is as a part of the village. Itachi is changing him - you can't deny that.
His death was honourable (Jiraiya's) - fair point, I'll agree with this statement.
That's irrelevant, had Itachi Totsuka'd Nagato at the begininng Naruto and Bee wouldn't be needed anyway. In fact, Itachi saved them from death with his Susano'o - I don't know what you're whining about. XD
Itachi saved the world, twice. Your entire argument has been shitted on, and I just iced the cake with this part.
