Filious

I actually have a question about the Demon Slayer. How does Demonbane work? I did about 30-60 per hit against demons, and about 100 per hit against the darkside loyalists with that sword. I got comparable damage with the flaming sword against these targets. I thought I'd do double damage against demons, but that doesn't appear to be the case. What's going on?

I've done the Taker, Barzahl, Awakened and Loyalist endings. I was wondering, if you kill everyone and are heavily modified, do you just end up getting executed?
