It couldn't be helped, due to the events of the episode Mugen had every reason to believe that the guy was a threat (to Fuu). Of course, the guy had actually befriended Fuu, but Mugen did not know that, and by the time that Fuu yelled for them to stop attacking each other, it was too late--Mugen had already launched his final, fatal attack against the poor guy.
