I know there is the pride of the warrior, but there is also the protectiveness of a triad-mate. You obviously did not want to kill Cyclonus, but Void had your will, and your terror, and that gave him immense power over your actions. I don't believe you tried to kill Cyclonus. I do believe that you tried to convince yourself that you had, for the sake of Void's probing, to hide pain from him that he would exploit.
