Are you serious? Shawn Michaels screwed over and embarassed Owen's brother! It would certainly seem reasonable for Owen to try to get some measure of revenge for it, whether he actually WOULD choose to do so or not. The family ties between Owen and Bret were very strong, so Shawn was understandably wary of putting himself in the ring with someone so close to Bret -- and someone who, through sloppiness, had already nearly paralyzed a wrestler in Steve Austin. I don't fault him for not going along with this Shawn/Owen feud. Yes, call it paranoia, but he was right to look out for himself and his well-being in this situation.
