Would it be spiteful not to help when you could because you can't stand the person in charge?

Would it be spiteful not to help if you knew you could because you could not stand the person in charge of the project? Say you were on a team building a float for a parade for the a pee wee team to have in a parade but the person in charge of the float you can’t stand because he is an arrogant twit with “small man’s” syndrome. You have skills that will make it turn out better and get done quicker and cheaper but you know this buffoon will try to hog all the glory and tell everyone it was his superior mind that saved the day, so to not help more than just biting your tongue and taking orders would be spiteful in the end? Or for the sake of the other decent people on the team you try to get your ideals done?
