Does Politics Turns a Good Man Into Evil Person?

Tweet

I know a lot of people who are so kind and righteous before. But when they enter into politics, something about them change. They start to become bad. They extort. They bribe. I am just thinking if we cannot blame them for what happened to them because of the influence of many people around them. Some say they cannot just resist the temptation. Does really politics turns a good man into a evil person?
