The hitman is certainly a killer and deserves to pay the consequences of his profession. Unless there is a policy reason to drop the charges against you, such as your testimony is necessary to convicting the hitman, I see no reason why you ought be treated as other than a co-conspirator. This is particularly true if, you are eagerly anticipating life insurance proceeds. Or double indemnity. Or to inherit her estate.
While you and I have crossed paths negatively in the distant past, on this point I concur, that justice requires a voice to be given to the innocent, and that penalties be meted out for “the hit man” as you say. Will also iterate again that anyone who advocates for abortion should NEVER be elected to public office. It totally cuts against the grain of civility and good order.
