How did hitler torture the jews?

He put jews in concentration camps. He also searched houses for jews.

By planting pre-existing  anti-Semite ideas into the heads of the German people, he basically separated them from the rest of civilization.(Note that anti-Semite idealistics are as old as the Jewish faith. Hitler did not invent it) First, he would make them wear yellow Stars of David and eventually moved them into ghettos. These ghettos were housing districts put aside for Jews to separate them even more from society. Then he decided to move some Jews into concentration camps. These camps were for labor and torture such as gas chambers and human experimentation. For example, in Auschwitz, arguably one of the most horrendous of the labor camps, Josef Mengele would experiment on Jewish twins.
