Depending on the source 85% were murdered in the camp. Purportedly 960,000 Jews entered the camp and were immediately killed, gassed or otherwise. So no, starvation and disease were secondary.
HE112, what a depressing and horrible subject. There was some sort of "selection process" when people arrived there, however, if I remember correctly all Gypsies were killed, no exceptions. Whenever possible I avoid all German products now. The Ukrainians along with some Balkan populations were also bad, that is why I do not care if Russians invade them now. For example, in early to mid 1940s Ukrainian Nationalists killed tens of thousands of ethnic: Poles, Jews, Russians,...... What is more shocking is they actually consider Bandera a national hero and sometimes even display red and black flags.
