The demons were so weak, and Kalant/the party so conveniently there at the right time (as lampshaded by the characters), that there's little chance killing Tyna was the goal of this move.

Desecration of Wings-inspired theory: Kalant didn't survive renouncing the power, but someone from the Tower used the opportunity to steal his identity. Hence why his aura is so strange: not because he used to be a Chosen, but because he is something else entirely. And he summoned the demons himself, as a first step to seduce Tyna.
