Why people always say Sasuke never lost a battle when...

[Pravin5]

You forgot the naruto rasengan beating sasuke chidori on roof. Plus killer bee fight also Raikage, mizukage, Tsuchikage def. Him.

Itachi vs Sasuke wasn't much of a fight.

yup but sasuke was so stupid that he charged in , actually he asked for a duel , so why wasn't it a fight

 

[WillToWin]

The first one, haku, and orochimaru weren't fair, even against gaara it wasn't fair only because he left the arena to become one-tails. Itachi beat Sasuke, unfortunately.

How does that change the fact if Sasuke wouldve used Amaterasu on bee from the beginning it wouldve never been a fight

A VERY IMPORTANT Part of a battle is estimation of ur enemy. Sasuke failed twice by underestimating his enemy and that counts as failure.

Also Bee might have escaped the amaterasu (He himself can cut or drop a tentacle cant he?)
