The evil part is where people are addicted to money, or the love of money, in this case, causing the "evil actions." It's important to know that money isn't an evil thing; it's people who do the evil deeds.
A lack of ethics and principles seems to be at the heart of the problem, since these individuals appear to look out just for themselves. That's why it's crucial for people to be informed about politics and demand accountability from their leaders. We need to be morally grounded and willing to challenge convention when doing so is necessary.
However, it must be kept in mind that not all people in authority are corrupt. Numerous individuals do their best to improve their neighborhoods because they care deeply about such places. Just that the actions of those who don't tend to eclipse those of those who do.
I don't think so, I think all authority are corrupt simply because they are human too, they also need to eat delicious food and use branded goods, and no one does not want those things. But some people are not too greedy, they know when to stop, so after corrupting everything they need, they will pretend to be a good leader.
Although I am also very upset when I see the leaders of a country corrupt, I do not want to blame or curse them because I believe that if we were in their position, we would also be corrupt like them. We get jealous because we don't get what they have.
