Why would he?

He had a working Eclipse Gate and used it to send his dead-and-revived-as-a-demon brother into the future instead of going to the past to prevent the death of said brother and his parents from dying.

If he didn't go back to change history then I doubt he'd do it now.

Besides, it might actually be a good thing if he did. It was after all what the Royals were trying to do too for the good of the world and at this point the situation is quite dour.
