I think you're using the word 'psychotic' to mean something it doesn't actually mean... A psychosis is comprised of hallucinations and delusions. If you thought a god of war was psychotic, I should say that was fairly scary. :p
Then what is the word I'm looking for. Although, if you believe Hollywood, Ares was quite psychotic...

But, anyway, I imagine Ares' temperament to be similar to my hubby's easily enraged, not so easily controlled once that rage hits. (Hubby is classified bipolar... but what I'm thinking of for Ares isn't quite the same...)
And a psychotic god of war, using the actual definition might be fun... creepy, but fun.
