That motivation should have nothing to do with humans though.
I just think this guy was a sick prick from the get go. The article did state that the boyfriend was known to police by virtue of him being an abuse victim. He obviously was left in that situation, or if removed continued receiving abuse.
Either way the boyfriend chose to continue the cycle of abuse. Which also means he was probably very abusive to her as well. It is well known that the majority of females who face severe abuse become extremely submissive.
How to break these cycles of abuse must be found, but how to do so and still maintain freedoms? It truly is a human tragedy, and this is yet another example of the results of that tragedy. At the same time both the boyfriend and mother are also examples of that tragedy. So now we are faced with dealing out punishment to victims of abuse, for the ultimate result of abuse, death, and in this instance, to a child. Of course we all want them to endure the severest of punishments, when their victim is a child.
So it becomes up to society as to how this is to be handled, which of course creates a problem when the different ideas are raised. Problem is none of the ideas that we have followed have produced the desired results, that being the end of abuse, and the end of senseless tragedy.
It comes into play with humans because rather than wanting the females’ attention to breed, they simply want the females’ attention - and the previous males’ children are just a distraction.
I meant to include you. Read #27.
