Science tells us that from the moment of conception the child is a human, and as we cannot say at what moment a child gains conciousness we must assume that it always has one (any other cutoffs are arbitrary). This means that you are weighing the value of two peoples lives and finding that an inconvienence is a greater problem than the death of a human, essentially that then means that every human life no longer has inherent value, only those who can or will fight for it (only the strong can belong mentality).
