Final answer:
Evil rulers killed people in their own country usually as a power display or to eliminate threats, seen in cases like Caligula’s tyranny post-illness or Ceauşescu’s killing of protesters before his execution.
Step-by-step explanation:
Throughout history, there have been numerous instances where an evil ruler resorted to killing people in their own country. This type of brutality was often a demonstration of power or a method to eliminate perceived threats to stability and authority. One such example is the Roman Emperor Caligula, who after an illness or possible poisoning turned into a tyrant, executing or exiling those close to him and partaking in extravagant construction projects to showcase his power. In religious contexts, instances of divine wrath or judgement, such as the biblical events where God is described to have allowed or commanded large-scale destruction, raise ethical questions on the righteousness of such actions. Furthermore, examples can be drawn from revolutionary periods, like the French Revolution, where counter-revolutionaries committed excesses in the name of quelling the revolutionary cause, or from the 20th century, where leaders like Nicolae Ceauşescu of Romania faced rebellion and eventually execution after his regime killed protesters. These examples illustrate a range of motivations, from consolidating power to ideological purging, behind such extreme actions by rulers.
