Boruto wants to protect the village, but he does the opposite. What more guilt can he feel after ruining the village to shreds, all with his own hands. And even though, he often relied on his heart, this time he relied on his mind and logic and this time, he will leave, if it means the safety of his village. This is kind of a second part to Boruto: The LAST so you have an understanding of what I believe happened in the past. But do keep in mind that this was written in January 2022 so events may not match up in the future.
