Some psychiatrists have said that she might have "self doubt" or she might suffer from a condition called "self hate" (Selbsthass). Selbsthass is a real condition and as it appears many Germans suffer from this condition. They cannot forgive their forefathers for WWI and WWII, the SS, Adolf Hitler and the Nazis. They have the deeply rooted belief that they are to blame.
Furthermore, Angela Merkel has no future to protect. She has no children and no sense and motherly instinct that she needs to protect her children. It is very well possible that she is part of the systematic dismantle of Germany and the European Union. The self-hate transforms into self-punishment and perhaps she and the rest of the self-proclaimed leaders of Europe know that the complete economical and financial destruction of Europe is imminent and cannot be stopped.
Perhaps the plan is simple. Create a mass migration, which is in fact an infiltration of sunny Islamic Jihadists that will destabilize Germany from the inside out, creating a sort of civil war and bring Germany to its knees. This will collapse the financial markets, destroy the Euro successfully and the "leaders" of the European Union, lead by Angela Merkel, can point the fingers at the Musslims and avoid admitting that the European Union was a failure they have caused. It's certainly a thought worth entertaining.
