I Complain About Wonder Woman

Steve's Death

If it's been a while since you've seen this movie, allow me to refresh your memory, before I start talking about what actually annoyed me.
So there's this deadly gas that can get through gas masks, which the German plan to use on the front lines. If they use it, it will kill EVERYONE in the battle, including the German soldiers. To stop that from happening, Steve takes the plane with all the gas and flys it really high up, before setting it on fire, killing him in the process (of course).

Now, while this is very heroic, and actually isn't just a lazy "how bout we kill him yaaay," as I would like to complain, his decision to kill himself while blowing up the gas was A REALLY BAD IDEA. Diana could have done it.
He said "I can save the world today, you can save the world tommorow" or something along those lines. And that's true, but he didn't have to die in order for her to make it out alive.
As Ares said, "Only a god can kill a god."
Diana wouldn't have died in the explosion. The explosion (as far as I know, anyway) isn't a god, therefore it can't kill Diana.
So, basically, Steve's death was completely unnecessary.

Now give me a moment to bang my head against a wall before I start another chapter to complain about something else.
