Just because you have a scratched headband it doesn't mean that you are a rogue ninja. That was an akatsuki symbol, not an rogue ninja symbol. Sasuke got his headband scratched by Naruto during VOTE1, but he didn't even have it afterwards, since Naruto returned it to him only after VOTE2.And that's the headband that Boruto is using, Sasuke's one. Also the vertical scratch from Boruto's headband clearly is because of something that happened to Boruto's eye, a sword cut or something.

I can see Boruto being driven to the dark side for a while, especially because of his conversation with Kawaki, but the headband wouldn't have anything to do with it.
