I'm afraid that if we do NOT listen to him, he'll come back next time possessing someone at a really bad time or place.  He's apparently got some serious power.  I think I'll go take the hit for the team...  Unless you all would prefer to spit in the face of a major chaos power.  I don't think he'll stop us from killing him after he has had his say... but if we don't at least give him some attention, we'll probably end up regretting it.
