They were beaten, robbed, starved and gassed
What were the tortures done on Jews during the reign of hitler?
They were brutalised, raped, imprisoned, separated from their communities, vilified, persecuted and humiliated in every way you could possibly imagine, and six million were murdered.
If you want to get inside the head of those Jews I'll attach a link to a poem by Yevgeny Yevtushenko. As far as I know it doesn't appear elsewhere on the Web (I have never been able to find it so I typed it up myself). It's very moving, very powerful, and it will go a long way to answering your question.
