The Amalekites Violating the Age Old Values of Humanity

The Amalekites violate one of the age old values of humanity across cultures. If you extend hospitality to someone, you've extended hospitality to someone. That's a value that goes cross culture in the ancient world. You don't do stuff like this. We will kill you given the opportunity and we will pick over your bones and take your things. And that's just not a good look.
