Yes, the person is a bad person according to our law which it can lead that person to spend some months in the prison, because that is the sources of the government income in every countries in the world. I don't think, is all government that used the taxes income to finance their family or their personal business, because there is a law that governed that aspect and if any administration found guilty of corruption in that area they will be punish for such attitude, because the taxes income belong to the people in that land which we called government. If you fail to pay your taxes as a citizen, I think it will be difficult for you to enjoy the benefits of your country because you will not have full right to enter some places in the country.
