Psychology behind it
Psychology of fetal experimentation
Sense of guilt
Fetal experimentation is merely one relatively small outgrowth of anti-life mentality, but their consciences continue to plague them. Fetal experimenters feel a little better if they can extract some good from the appalling carnage that the abortionists are wreaking.
William Gaylin and Marc Laape of Biological Sciences at the Hastings Institute, displayed this nagging sense of guilt when they claimed that:
Since we know we are going to destroy, dismember and discard the fetus in a procedure known as abortion, it seems a small indignity to expose it to rubella vaccine just prior to that termination...
The medical ethic 'do no harm' would, of course, be violated, but we have already violated that principle when we accepted the concept of abortion. The ultimate harm of destroying the fetus trivializes that which precedes it.

Contrast this type of attitude to that of Dr. Andre E. Hellegers, Professor of Obstetrics and Director of Georgetown University's Kennedy Institute for the Study of Biomedical Ethics, who has identified the attitude that researchers with morals should have;
No one can give consent for research on an aborted fetus. To ask a mother who is seeking an abortion to consent to an experiment on the fetus is meaningless...
It would be like asking consent from a parent who had abandoned or battered a child. To me, it's like a Nazi saying, 'Since we're going to put all those Jews in the gas chamber anyway, let's get some good out of them by doing medical experiments first."

NAZI Ideology
Of course, Nazi doctors did say these things in their own defense during the Nuremberg trials. Dr. Julius Hallervorden testified that he said;
"If you are going to kill all these [Jewish] people, at least take the brains out so that the material may be utilized."

This guilt has grown enormously in scale as the death toll mounts into the tens of millions, and only more and newer promises of "beneficial" experimentation will soothe it. Of course, such guilt grows exponentially. Researchers search desperately for new uses for living fetal tissues; Parkinson's Disease, Alzheimer's Disease, spinal cord and brain injuries; juvenile diabetes, retinoblastomas, and so on.There are at millions of cases of the above diseases and injuries in the world today. Even though there is no solid evidence that fetal tissue transplantation will help anyone, just the possibility of helping all of those people helps assuage the massive guilt somewhat.
