Murder is the killing of a human being. A human being is breathing and sentient.
I'd say it's much more cruel to bring children into this world who no-one wants, no-one cares for, who are just exploited and discarded.
Do you have evidence for the existence of the soul?
The Bible says life begins with a breath.
Have you given birth? Carrying a pregnancy to term will change your body for ever. Giving birth might give you scars for life. A caesarian also scars your body for life, and who's going to pay for the premature care for the baby; you? That's why you don't "have de baby". Besides, how many unwanted children have you adopted? There are already millions of children who no-one takes care of in this world. Once they all live happy and healthy lives, THEN we can worry about blobs of cells with no functioning nervous system.
Again, murder is the killing of a living human being, and, again, the Bible (in which the Ten Commandments can be found, twice, in different orders) says life begins with a breath.
