Why did Yuxin Mei Wang abduct her children?

One psychologist offered that "An abducting parent views the child's needs as secondary to the parental agenda which is to provoke, agitate, control, attack or psychologically torture the other parent. It should come as no surprise, then, that post-divorce parental abduction is considered a serious form of child abuse." according to Dr. Deirdre C Rand: The Spectrum of Parental Alienation Syndrome, American Journal of Forensic Psychology 1997: Volume 15, Number 3 and Number 4. Wang recently filed an Affidavit in the US where she said the divorce dragged on for 3 years. It did indeed because she and her attorney refused to settle. Three (3) offers of settlement was offered so that we can focus on the wellbeing of the children but she refused. It was discovered in February 2008 that Wang was not divorced from her previous husband. In August 2008, the final offer of settlement was made which included a sum of money to be paid to her. Similar to the recent case in Singapore, a bigamous marriage is void from day-1 and there is no community property. Yet Wang still refused to settle where she could walk away with a sum of money. Her "parental agenda" came first.
