I know that even rational, intelligent, thoughtful people can go off to odd places when they believe God is involved. If someone truly, honestly knows in his/her hert of hearts that God said to do something, that they were chosen for this task and required to do it no matter what, even the awareness that it's against the laws of the nation may not stop them.

Would a loving parent sacrifice my child for her (the parent's) eternal salvation? Probably not. Would that same parent sacrifice the child for the child's eternal salvation? Hard tellin'.
