Last month, my friend was watching the show with me where Itachi slaughtered the entire family. Of course he was shocked at the result Itachi did, so he came up with his theory. He came to the conclusion that Itachi may be on the "good" side. His unique reasoning would be that maybe the parents or entire family could have been planning an evil trap for the kids or to destroy Konoha village. Little did we, the audience, know of their intentions. Itachi could have found out and didn't want to traumatize Sasuke in thinking that his parents turned out to be awful people. And Itachi could be hiding a secret to Sasuke to protect him, regardless of the terrible things we've witnessed between the 2.

Could this theory work out???

It doesn't to me, I disagreed with my friend.
