Forgiveness is devine. We can hang Adolf Eichmann and other mass murders and still forgive them.
The idea of Pro-lifers being buddy-buddy with this killer make sme sick. Yes, he can help the Pro-life cause, but it is tainted help.
Using this guy to help the Pro-life cause gives lie to idea that the Pro-life movement is a morals based movement. The concept of "the end justifies the means" is the founding principle of abortion. The end justifing the means has no place in the Pro-life movement. (IMHO)
