1. Power and Influence: In certain societies where women held positions of power and influence, a lady might play a key role in the decision-making process. She could persuade the king's advisors, family members, or government officials to support the idea of regicide.
2. Conspirator: Ladies could be trusted confidantes and potential conspirators. They might be involved in secret meetings, planning, and providing resources for the plot to assassinate the king.
3. Seduction: In some cases, a lady might use her charm and allure to manipulate and gain information that would help execute the murder plan. She might become romantically involved with the king or someone close to him, thus weakening his guard.
4. Betrayal: A lady could feign loyalty and gain the trust of the king or his inner circle. This would provide an opportunity to betray him and facilitate his assassination from within.
5. Moral Influence: In some instances, a lady could serve as a moral force or voice of reason. She might express concerns about the king's rule or policies and try to influence the decision to murder him based on moral principles.
6. Figurehead of Rebellion: In situations where the king is perceived as tyrannical or unjust, a lady could become the symbolic figurehead of a movement or rebellion. She might inspire and unite people who want to overthrow the king.
7. Silent Accomplice: In cases where the lady does not actively participate in the murder plot but knows about it, she might passively support the act without directly taking part in the execution.
It is important to note that these are just a few possible roles and generalizations. The specific role of a lady in such a decision would be influenced by social, political, cultural, and historical factors that shaped the society in which she lived.
