Klaas argues that certain personality types, like narcissists and those with psychopathic tendencies, are drawn to positions of power. This means that the pool of individuals seeking leadership roles may already be skewed towards those who are more likely to abuse their power. 

Even individuals who initially have good intentions can be negatively impacted by the experience of holding power. Studies and research suggest that power can alter brain chemistry, leading to increased risk-taking, a sense of entitlement, and a decreased ability to empathize with others. 

Klaas also points out that the way we select leaders is often flawed. We may not always choose the most qualified or ethical individuals, and the process itself can be manipulated by those seeking power. 

Once in power, leaders may not be held accountable for their actions. Weak institutions, ineffective checks and balances, and a lack of transparency can allow leaders to act with impunity, further exacerbating the problem.
