And the young man did not delay to do the thing, because he delighted in Jacob's daughter. Now he was the most honored of all his father's house.
Genesis 34:19

Based on the ages and timelines given in Genesis, Dinah was a young teenager when she was abducted by Shechem, probably between 12 and 16 years old. Shechem was a manipulative rapist and the most honored man in his father's house. Serious parenting fail. Not all badly behaved children were made so by their parents, but clearly Shechem's father was a contributing factor here. #vayishlach
