I've seen many people during all these years calling Sakura and Hinata selfish because of their love.
Since when wanting to be with the one you love it's selfish? Since when wanting to protect the one you love it's selfish? Since when wanting to save the one you love from the darkness is selfish?
So Naruto that wanted and saved so many people it's selfish?
So Naruto's parents who stood in front of the enemy and protected him are selfish?
Those two girls are so far from to be called selfish. Sakura never wanted to make Sasuke hers she just wanted to save him from his darkness. Even when he tried to kill her she still wanted for him to be happy and move on from his past.
Hinata sacrifice her life for Naruto's sake. She gave up on her own life for him. She had been admiring him for years from the shadows and all this turned into love, so she wanted to spend more time with him and that's not wrong at all.
