Dairen Is the only good guy on the Sailor Moon anime. He is also (in my opinion) one of the better looking charecters on the show. Darien, aka Tuxedo Mask, and the love of serena's life, isn't exactlly all good. He's done some bad things in his time. He's said things that made Serena really depressed, almost caused the breakup of the sailor scouts, and at the end of Sailor Moon R almost destroyed the universe. Some hero!
