In Euripides' *Hecuba*, even Agamemnon--a remorseless war criminal--was incensed to learn that Polymestor had murdered a guest; no matter how Polymestor tried to frame it as a service by killing the last heir of the King of Troy known to have survived, even Agamemnon had SOME standards.
In Dante's *Inferno*, those who betray guests or hosts are the second lowest of the low.
And to this day, hospitality is regarded as sacrosanct in many cultures.
