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.
I lost everything once…
...خسرتُ كلّ شيء ذات مرة
Ich habe einmal alles verloren.
Una vez lo perdí todo.
Una vez lo perdí todo.
Ho già perso tutto una volta...
Eu perdi tudo uma vez...
Я однажды лишился всего.
