According to those who believed in legalism who must have absolute power and why?

According to proponents of legalism, absolute power must rest with a strong, centralized authority, typically embodied in a ruler or government. This is because they believe that strict laws and harsh punishments are necessary to maintain order and control in society, as human nature is inherently selfish and prone to disorder. By concentrating power, legalists argue, a ruler can enforce laws consistently and effectively, thereby ensuring societal stability and harmony.
