Are embryos in a freezer alive and human? Should the person who removes the power be charged with murder? Is a brain-dead person worthy of the same protection? I'm asking these questions because I believe that all of humanity should be respected and I don't think we can protect entities without essential human qualities without diminishing or even losing that respect.
In my opinion the qualities of human form and human thought (or at least the beginnings of human thought) should be protected.
Yes.
Should the person who removes the power be charged with murder?
Yes. Don't be screwing around with things you don't understand.
Is a brain-dead person worthy of the same protection?
Irrelevant question. You have already stated that the person is dead. Their body just hasn't gotten the message yet. The person's body will eventually shut down because the brain can no longer support life. An embryo is completely different as it is developing it's brain as per the miracle of life. You cannot equate a brain dead corpse with a developing embryo.
