Although I don't necessarily think he's evil, I'm fairly surethat Dashiva will go completely mad in the next book, and will kill or wound someone very close to Rand in the process. We all know how much Jordan likes to draw from various mythologies in his series, and Dashiva's name is a little too close to the Indian "Shiva" (the destroyer) for mere coincidence. Along those same lines, I think it will be Narishma (close, albeit a stretch, to Vishnu) who either contains or kills Dashiva. I also think that as a group, the Asha'man will start to deteriorate in PoD. All along we've heard how Saidin drives men mad yetwe've never really seen one. Lets get crazy.
