That doesn't mean you are in the right , he is allowed to kill dclass not cuffed in lcz , if anything i would have thought you were CI and try to cuff you / kill you
First time can be justified , second kill is just revenge rdm
Also
Explain how this isn't rdm and going rogue as foundation , your argument of wanting to give them a tour is not valid here , you literally kill a sg for doing his job
Anyway should be a warn
