i respect narutos decision.. and it's his ninja way.. also you felt that he wanted sasuke more than sakura because of what he wanted to do.. but first of all.. he doesnt show that same urge for sakura simply because sakura did not do something for naruto to save her back ( unlike sasuke who lalready lost his path)... while naruto exerted much effort for sasuke because he knows he still can save him back... he understands sasuke more than anyone.. same with sasuke no naruto..
