You said it was first degree murder, then said you were citing canon law.  First degree implies the existent of at least one other degree.  If there was no second degree murder, then you would have only murder and other offenses.  If you are misrepresenting the content of canon law, you really should stop.  God will judge those who mock his Church.   Perhaps you find it amusing to misstate canon law, but it really has no place here.
