Why do humans only learn to regret when everything is over? His demice was coused by his own arms. So he didn't want to return, becouse he wouldn't have a place to stay even if he returned. But royalty, who died besides him, asked god to send his feelings back to the time, when he was just ordinary human. And even if he didn't wanted to revive again, his future experiences let him change his past.😎.
