From your reference [6] (page 62), someone connected to Trump said, "The person can get the emails which 1. Were classified and 2. Were purloined by our enemies. That would demonstrate what needs to be demonstrated." So the plan was to gather evidence that Clinton had committed a crime (allowing classified information to be obtained by a foreign adversary). Are you saying that trying to prove your electoral opponent is a criminal is not allowed in a democracy? That that is, as you say, "a clear case of violating democratic rules"? You think the Trump campaign should have just ignored the possibility that Clinton's conduct was criminal, since thinking such things isn't nice?
