It thematically plays, considering a) the Hashashin he led served as a military threat to the world powers of his time, as well as b) factoring in King Hassan's Inadequate Inheritor view of his "inferior" clones/successors—the very same relationship Big Boss had with Solid Snake in the original 8-bit MSX games.
