Cute.If they don't know about and are not allowed to talk about it then how will they ever learn about it, your logic is flawed shut up wipe your tears go to sleep and get over it in the morning.
You just made my point below:
You do realize that's not even close to the same thing right? Gaara was controlled by a demon, sasuke was just an emotional teenager letting his gut reaction dictate his actions and choices, Sasuke acts on the most basic instincts without much consideration.
Then we have that no one tried to kill Sasuke for being alive, in fact his brother went out of his way to ensure Sasuke's survival when someone did try to kill him for simply being an Uchiha. Gaara had to endure countless assassination attempts from his own father and when they failed from his closest "friend" that'd be equivalent to Itachi trying to kill Sasuke multiple times.
Gaara had no one who wanted to talk to him or anything to do with him. Sasuke rejected everyone despite having many girls who wanted to talk to him and a few males who wanted to be rival/friends with him.
