Obviously major spoilers ahead, please don't read if you haven't seen the movie.
We are told towards the end of the movie that Diana is the god-killer, since apparently only a god can kill another god, and with what we saw in the movie, it would appear that Ares is dead. We are also told that Ares killed all the other gods. So since Diana is a god/demigod, is anything able to kill her now?
To be clear, I am asking with the assumption that Ares is actually dead and does not somehow come back to life.
