The most shocking part of Craig's "justification" is this:

So whom does God wrong in commanding the destruction of the Canaanites? Not the Canaanite adults, for they were corrupt and deserving of judgement. Not the children, for they inherit eternal life. So who is wronged? Ironically, I think the most difficult part of this whole debate is the apparent wrong done to the Israeli soldiers themselves. Can you imagine what it would be like to have to break into some house and kill a terrified woman and her children? The brutalizing effect on these Israeli soldiers is disturbing.

Surely this puts the religious stand on abortion in a different light? Aborting foetuses is merely sending them to eternal life a little early?

This is why theology gets no respect from me; it's an attempt to defend the indefensible. The irony is that Craig repeatedly claims that without God there is no foundation for morality.
