I don't think someone ready to murder people to take their organs will have problem with finding ways around "consent". In fact, if more organs are available, it should limit the need for a black market. Imagine you are rich and in desperate need for an organ. You are not fundamentally evil, but you are really desperate, losing morality and ethics as the disease progressed. If someone can find you an organ before you get to murder then it will save the life of an innocent and your sanity, and maybe also your own life too, for the quicker response.
