Kilowog and Drax the Destroyer

It will be interesting to see how Drax is portrayed in Guardians of the Galaxy, Vol. 3.  Killing Thanos was his life's goal, but when that was achieved, he was merely a bit player in the action.  How does that affect him and what will he dedicate himself to now?  One rumor I have read is that he will discover that his daughter still lives, so perhaps his new motivation will be in finding where she is.
