It was also suppose to strengthen the bonds between Gao and Baztz which we see;

Battz must of planned to leave Gao as soon as possible in the beginning but after fighting by Gao's side so much it showed that Batzz was hesitating and in deep thought over leaving or not. And now that bond, and the fact a new much stronger monster has showed up, Batzz will return to fight with Gao again.

If they didn't do any of this and tried to free Batzz because they needed him, then given what we know of his personality he would refuse and nothing Gao or anyone could do would change his mind. Now he has reasons to return because he went though all that.
