I really didn't see the need for Kurt to be involved with the occult and demonic forces any more than any other X-man. His appearance shouldn't dictate his involvement, it'd be like expecting the Beast to deal with any animal based threats because he's got fur and claws, or Cyclops to deal with anything involving eye-beams.
That aside, I love this confrontation, and Kurt acts in precisely the way I'd hope a hero would.
