1 Rukia Kuchki
Rukia has a sad past. She never got to meet her sister, then lost her own mentor to a hollow. She had it rough.
2 Naruto Uzumaki
Naruto Uzumaki is a fictional character in the anime and manga franchise Naruto, created by Masashi Kishimoto.
3 Gaara
Gaara is a fictional character in the Naruto manga and anime series created by Masashi Kishimoto. He is the jinchuuriki of the one-tailed shukaku and can control sand that is stored in his gourd. Sure, his backstory was similar to Naruto's, but it's the differences that set him apart. Gaara was considered a monster by not only his village but his family as well. His uncle tried to kill him on orders from Gaara's own father.
I think the fact that he had a family but was treated as he was is more tragic than Naruto's situation. Gaara was even led to believe by his father that his mother had hated him and that he was responsible for her death. Think about all that verbal abuse coming from the family who is supposed to love you. No wonder Gaara was so messed up and unstable.
4 Sasuke Uchiha
Sasuke Uchiha is a fictional character from the manga and anime franchise Naruto, created by Masashi Kishimoto. I honestly feel like if I were to choose, I'd say Itachi had a sadder backstory. Sure, Sasuke saw the dead bodies of his clan, but Itachi had to actually kill them and his parents, all for the sake of the village. Everyone always says poor Sasuke, but I feel that Itachi is the one that had it more rough. Forced to make an impossible decision between his village or clan, then he had to leave his village and join a cult to spy on for his village, all while he was still a teen. Finally, he dies without his village knowing of his sacrifice for them.
At least Sasuke found out about Itachi after he died, but Sasuke was a bystander for his clan's murder, while Itachi was forced to be an active participant. Itachi was a hero to his village, but no one knew or acknowledged this while he was alive. He was treated as a traitor for following orders and putting the lives of the entire village before his own clan or emotions. He was like the shadow Hokage.

8 Nico Robin

9 Jellal Fernandes (Fairy Tail)
Jellal Fernandes is a childhood friend of Erza Scarlet. When he lost his own memory, he was a Dark Mage who desperately sought to revive Zeref via the R-System. Jellal served as the main antagonist of the Tower of Heaven arc and is currently a member and co-founder of Crime Sorcière. His past is way worse than Erza's because at least Erza has her friends and Fairy Tail, plus everyone loves and idolizes her. Meanwhile, Jellal had been controlled for most of his life, then had to either go to jail or be relentlessly on the run as a fugitive, facing the risk of being caught all the time.
10 Itachi Uchiha
Itachi Uchiha is a fictional character in the Naruto manga and anime series created by Masashi Kishimoto. Kill your own family just for the good of your village, but the village that he saved treats him like a criminal. It's more painful that you killed your own family just for the sake of a village that betrayed you. I think he should be in the top 3 because Sasuke just watched his family die but the village accepted him.
I feel like having to kill your own family is much worse than watching your family get killed. Sasuke shouldn't be so high up.
