Good point, people should not blame the mother.  Wonder if the mother had not left Oahu to go to Greece and continued to drop and pick up the son from Aikau, Aikau would have murdered BOTH the son and his wife, then committed suicide.  And yes, despite Aikau's history of violence and drug use, the family would naturally back up and do whatever they can to keep him out of jail or prevent him from losing visitation rights of the son.  The wife might have been scared for her own life, which was an accurate assessment but at the time, I am sure she felt Aikau's anger and violence was directed only at her and NOT their son.  Maybe she felt some assurance that Aikau and his son lived with other respected family members together so she felt some additional assurance her son would be safe when she left for Greece.  Unfortunately NO one predicted, not the wife, not Aikau's family members that Aikau would take it to an unimaginable level of murdering his own son before committing suicide.
