When it comes to identifying backstabbers, there are several synonyms that can be used. One of the most commonly used synonyms is "traitors." This term accurately describes someone who betrays the trust of others, often for personal gain. Other synonyms for backstabbers include "double-crossers," "betrayers," "turncoats," and "two-faced individuals." Each of these terms highlights the fact that these people cannot be trusted and are willing to deceive others to advance their own interests. It is important to remember that not everyone who seems friendly and supportive on the surface is trustworthy, and it is wise to be cautious and observant when dealing with others.
