Everyone Knows the tragic story behind the death of Naruto's parents.
The loving story of the sacrifice of a mother and father for their village and their son. Kushina and Minato(The 4th Hokage) died sealing the 9 tails inside the body of Naruto ( their newborn child ) after Madara set the 9 tails free to destroy the Village of Konoha.
Their death left Naruto an orphan, with the Village people taking care of him.
However, Naruto thrived, not knowing anything about his family until later in the series ( Naruto Shippuden ). He followed his dreams of one day becoming Hokage and earning the respect of the people of the village. (nothing makes me more proud :'C )
Edward and Alphonse Elric ( The two Alchemist brothers ) Lost their mom at an early age due to illness. They were left alone since their father had not been present in their lives after he left the house.
The two young alchemists in fear of being left alone decided to bring their mom back to live, breaking the forbidden rule of alchemy which is Human Transmutation. Bringing back the dead or creating a human from alchemy.
However, due to sadness and despair, both of the boys didn't listen thus resulting in them having to pay the price for their actions because of the Alchemy law of equivalent exchange which states ' Humankind cannot obtain anything without first giving something in return. To obtain, something of equal value must be lost'.
Alphonse lost his body and Edward lost a leg. In order to bring Alphonse back, Edward bound his soul to a metal armor resulting in him giving up an arm as something of equal value.
In the end, what they created was nowhere near being human.

If you watched Naruto then you must know about the Uchiha clan, the brothers and the amount of death that revolves around the Uchiha clan.
After Sasuke's brother, Itachi completely whipped out the Uchiha clan including their parents. Itachi left Sasuke alive and told him ' If you hate me, get strong enough to kill me' or something like that.
Sasuke surely went down the wrong path, consumed by revenge he left the village of the hidden leaf to search for greater power in order to be able to kill Itachi and avenge his family and clan.
The series later reveals the true reasons why Itachi annihilated his whole clan for the fucking sake of the goddamned Village. There's only one thing I can say and that's that no one deserved more happiness in the series than Itachi and Neji, oh and Obito too (who is also part of the Uchiha clan).
anyways, Sasuke later at some change of heart decides to fight in the 4th great ninja war against Madara and Kaguya, in order to later become 'Hokage' or so he said. which aka, never happened. Instead, he fights in the shadows to make sure things don't get out of hand.
