Since Uchiha Shin is just a kid

[ShadowACS]

maybe he turns good

 

[SenseiSama]

You would expect Sasuke to take him in and train him as a Konoha-nin or something but...

Sasuke is already Boruto's sensei :|

I know but Sasuke is a Sage now so he's not really living there and Konoha accepts anyone these days since the villages are united. Also, Sasuke should get an assistant like Oro had Kabuto and Tsunade had Shizune.
