I respect her because instead of giving up, no matter how weak and useless she knew she was to Team 7, she made herself become stronger. She trained hard and saved many important lives. Her intelligence helped in the war, as well as save Kankuro from Sasori's poison that seemed incurable. She may not be the strongest or fastest, but she has played a big role in many other lives and despite her devotion to the Sasuke she believes is still hidden within the darkness, she even stood up to him when he attacked Naruto. She's human and made many mistakes, but she made up for it, like all the others who made mistakes.
