If you agree with what I propose then work towards that rather than the continued legality of killing on purpose that which we can work to save.If you know the result of an act WILL be death... it does not matter what your purpose was. That does not change the amount of complicity in the deaths.
I agree with your plan and would support it over the current law. But based on your logic by supporting your proposal, we would both be complicit in the deaths of these lives.
