Hired assassins are individuals who are paid to kill someone on behalf of someone else. There are several synonyms for this term, including "hitmen," "contract killers," "guns for hire," "mercenaries," "professional killers," and "death dealers." These terms are often used interchangeably with hired assassins and share the same connotation of violence and illegality. However, it is important to note that these terms do not portray the true nature of the work done by hired assassins or the gravity of their actions. Ultimately, regardless of the synonym used, hiring an assassin to commit murder is a serious crime and should never be condoned.
