In the conflict scene between Wonder Woman and Ares we are left feeling that she has defeated him. However, all we really know is that Ares is no longer around and there is a rather large crater where he used to be.
But, Ares is supposedly immortal, you don't just kill an immortal being. Also, he is supposed to be a major adversary of Wonder Woman's.
Killing him off in the first WW movie seems silly.
So my question is, did Wonder Woman defeat Ares by killing him or did she simply send him away momentarily?
