defector

A defector is someone who abandons their allegiance to a particular group, cause, or country, often to join an opposing side or pursue personal interests. This act of defection typically involves leaving behind existing loyalties or commitments, and it may be driven by various motives such as political disagreement, ideological difference, or personal gain. Defectors are often viewed differently depending on context; some see them as courageous, while others consider them traitors. In summary, a defector is an individual who switches allegiance from one group to another, usually in a significant or consequential manner.
