Sasuke’s defeat to Gaara, and later Itachi, forces him to realize that he is not strong enough to get revenge against his older brother.
There is no value in killing you now,
my foolish little brother.
لا قيمة من قتلك الآن يا أخي الصغير الأحمق
Ustedes no vale la pena ni siquiera matarlos.
A vosotros no vale ni la pena mataros.
Non vale nemmeno la pena di ucciderti,
Não há razão para matá-lo
 agora, meu irmãozinho tolo.
Ты недостоин того, чтобы тебя
 убить, глупый младший брат.
