A ruler with absolute power, often referred to as a dictator or autocrat, has the authority to make decisions without legal constraints or checks and balances. This concentration of power can lead to significant control over the government, economy, and society, potentially resulting in both swift decision-making and the suppression of dissent. While such rulers may implement policies effectively, they often face criticism for human rights abuses and lack of democratic governance. The absence of accountability can create an environment of fear and oppression among the populace.
