Ironically, the person most responsible for the deportations and deaths of Hungarian Jews during the Nazi occupation was a Jew, Erich Kastner, a so-called leader of the Jewish community. Kastner and other Jewish leaders were warned about what really awaited the Jews at the exterminatation camps by two heroic escapees from Auschwitz. Kastner used the information to get his own family and a select group out of Hungary, and concealed the information from the rest of the population, allowing hundreds of thousands of Hungarian Jews to go blindly into being slaughtered.
Kastner went to live in Israel, where he was assassinated for his heinous crimes in Tel Aviv in the mid 1950s.

The person most responsible for the deportations and deaths of Hungarian Jews during the Nazi occupation was Adolf Hitler, whose grandfather, so it is said, was Jewish.
