Well Medea's soul fragment incarnation killing each other isn't that odd i would say, if we factor in other points.

As at the end (as per the WN), all of her soul fragment incarnation merged together with the Medea's soul fragment incarnation of Glass' world and formed the physical vassal for Medea's main original soul to take over.

In a way, we can say that the relationship between Medea's 'soul fragment incarnation' is similar to the relationship of the "soul fragment" of "Gaelion" (Dragon Emperor) in the WN. Gaelion did go around with Naofumi to kill those who had a fragment of his soul and absorb them.

So, we can say that the fragments killing each other off might be a sign of merge that occurs between the worlds, and the stronger soul fragment incarnation remains while the weaker one gets absorbed, eventually giving Medea a perfect body to possess at the end.
