"the only dates we remember are the children's mother's birthday which we celebrate with a cake" Too bad you didn't remember your divorce date in which you were given notice to "leave her alone" or the date she called 911 to tell them that he was "trying to kill her"...too bad the jury didn't believe the word of the dead woman in court tapes!
The whole affair is a enormous mockery of God, of course. On a serious note, the theologian John Calvin had an interesting comment on the fact that evildoers sometimes get away with their wickedness in our fallen world. To paraphrase:
Don't fret about evildoers who escape justice! It's actually a very bad sign for them that they are allowed to escape judgement in this life, for they are merely being fattened (with their wickedness) for the day of (ultimate) slaughter.
One day, this hero of degenerates will face a judge who knows the complete truth of what took place, who knows every single thought that went through his mind as he did what he did. God will not be mocked forever. Dies Irae.
