Serious question.
They have so many disgusting traits for example lactose intolerance, schizophrenia, tendency to homosexuality, atheism, opposition to gun ownership, fecal obsession, gastrointestinal problems.
It’s impossible to think they are made in the image of God in fact they are more closely resemble Satan than God tbh.
Your guess is as good as mine. Could it be some are just genetically evil? Could it be a Canaanite or Edomite bloodline issue? I don't have a good answer to that.
