Would any of your family members become stronger no matter what so they can avenge you and the rest of your familis massacres if your older sibling killed everyone even if they the world is turned against them?
After finding out the truth of why your older sibling killed everyone,would they then hunt down the people responsible for your families massacre,and kill them for using your older sibling?
Sasuke>Your family.
But, he never avenges his family. That's the point. Kishimoto defeated the purpose of the character.
Awww. My comment got to you. Even though I wasn't being entirely serious and I actually like Sasuke's character. Lol
If it helps you, then sure.
