Well, you're the one claiming that it was simple and without caveats.
But taking life without the express purpose of self-defense is murder or manslaughter. And you characterized abortion where the woman's life is not in danger as the taking of life without the express purpose of self-defense. And, given that a non-spontaneous  abortion could be considered premeditated, it follows from your own reasoning that one has to consider abortion to be murder. Either that or it isn't as simple and without caveats as you make it out be.
