After some corrupt officials are sacked, or they denounce their power and let them fall, or regret that they went into the wrong way and chose the wrong path, they should not be officials, or they told their children "never do politics". Is politics really a "high-risk occupation"? Obviously, it is a public office serving the people. How can it become a "trap" that mistakes oneself, or even an invisible "weapon"? Once corruption is caught, all faults are blamed on "power" itself, revealing the nature that cannot resist temptation, can't keep clean, and is easy to corrupt itself. Regarding this text, what is the following understanding? ['Politicians should adhere to integrity.', '"Absolute power leads to absolute corruption", once a person has power, he will inevitably go to corruption.', 'Politics is a high-risk occupation that can easily lead officials to corruption.', 'Compared with professions such as doctors and teachers, politicians are more responsible and riskier.']
