"All success is quite temporary if you don't work hard enough to maintain where you are. Talent can get you somewhere but character keeps you there. You have to build character along the way and know when and know how to take the victories from situations even though they might seem grim."

Things do look pretty grim, but I think there are more laughs in Hellboy in Hell than there are in B.P.R.D.: Hell on Earth. I think Hell is getting nicer and Earth is getting worse. Once we figured out what we were doing, the whole point of the Hellboy/B.P.R.D. stuff has always been evolution. The kind of evolution we're seeing on Earth is nasty evolution - part of this kind of evolution is that you have to wipe out what was there before you can replace it.
