Well the difference so far between Clarisse and Octavian is that Clarisse was given moments where the reader could see she wasn't all bad. I mean she starts to open up more to Percy during The Sea of Monsters and even asks if they are friends during The Demigod Files. Octavian on the other hand has been shown to blackmail people so he can get what he wants, actively defying the current leader of the camp (and possibly trying to overthrough her), and is currently leading an attack against Camp Half-Blood. He may have also killed Gwen simply because his cohort was shown up by the Fifth Cohort during the War Games. While he may not be a bad guy, he is still a bad guy.
