Well I think that's surely how he should react then. You have my permission to take a swing at Parkun if you wish, if there's a plausible way for Kuric to hit him without killing him...don't think I want him dead yet.
Maybe the rest of the group/some of the group could find Kuric just in time to hold him back (physically restrain him)? Or Kuric continues his charge, and...the trap is sprung early? Not sure if everyone will want things to go that way though.
