I am trying to understand whether you mean kill him and live free, or is it kill him and not free. I will answer it the way i think i understand it. what is coming out of this sentence, is a consequence. Its feels like someone is being given an ultimatum here, they need to choose what they want to happen to them. let me give an example, lets say this is a couple that has been together for while, but they have been facing challenges. Maybe the woman has been constantly abused by her husband and when she consults her friends on the matter, she is told, just get rid of this person and finish your worries. In other words to be free of this abuse just kill him, and you will not have to go through this kind of pain again. it's a choice someone is being given to choose.
