Just a badass theory I thought of because it makes the dynamic between boruto and kawaki just that more interesting. Reminds me of naruto/nagato but still interesting. Sasuke trains kawaki who uses his power for his own twisted sense of good. Sasuke can't bring himself to put down his student and gets owned. Naruto gets wrecked too. It's up to boruto To take down Sasukes last mistake. Both prodigies of Sasuke fighting for the good of the world
