Answer:
the hatred for jews was already very common especially with the mayor being anti-jewish. when the first world war that he was in, many soldiers and hitler could not take the defeat and lost so they blamed it on the jews and "enslaved" them. they said that the jews betrayed them and they are backstabbers so for that they should be punished. when hitler blamed the jews for their defeat he created a stereotypical enemy. according to the nazis killing the jews would have solved all of the problems in germany.
