I'm always hesitant to comment on this type of ****, but what could the mother have possibly done to enrage him to the point that he'd endanger the life of the baby, let alone lay hands on a woman? Coming from a father who almost lost his baby daughter for no other reason than "nature", this is ******* horrific.
Then you step back and consider the plight of a young man who's ceiling just went from probably making the League for a few years and earning life-changing money for his family, to likely going to prison for 10-20 years, his children growing up knowing what he did, and hoping he can land a job flipping burgers when he gets released.
