The reason Jews have been perceived as evil is because they are very community guided as for the longest time they’ve been roaming through Europe and the Americas with no country of their own
The reason they are seen as evil is because back in old days when Europe was strongly Christian in the bible it is immoral to loan money to ppl
In Jewish faith loaning money to non Jews is ok tho so Jews became oversaturated in the banking markets
And ofc ppl hate money loaners and rich ppl Jews have essentially been trained for generations to hoard wealth
