They'll justify it the same way they justify having a serial killer leading the team, that everyone no matter how far into darkness they may descend can find their way back. Oliver has done some dirty shit and honestly while I know Adrian is a lunatic, his anger isn't entirely unjustified. Oliver killed dozens if not hundreds of people and while they were criminals, it wasn't his call to play judge jury and executioner. Quite frankly I'm amazed there isn't a thousand Prometheus's plotting revenge. After that episode I realized how much alike Oliver and Laurel-2 were but the difference is Oliver killed criminals whereas Laurel-2 killed civilians, and I think that's also why Oliver wants to prove Laurel-2 can change because he sees in her what he could have become.
