The baby was born pre-maturely, apparently the family did not inform him that she was born, he died not knowing that she was born. It’s likely the due date fell on a date that he thought he would be back in time for, the decision to go was most certainly discussed with his wife and family which they were okay with or he wouldn’t have gone.
As I said above, any man worth his salt knows where his real responsibilities lie, and it isn’t with pursing his own fun at the peril of his family. It doesn’t matter whether he had talked his wife into it. It doesn’t matter that she packed his bag. It doesn’t matter that the child was born early. Priorities matter, and it’s obvious his were with his own pleasure not with being there for his family.
