double-crossers
Those who betray
Double-crossers are people who betray others after feigning loyalty or agreement.
The term implies deliberate deception—someone who double-crosses pretends to be on your side while secretly working against you: The heist fell apart because one of the double-crossers tipped off the cops.
The word carries strong contempt.
