Right and wrong always matter. The result of wrong is oppression, repression, corruption, depression, dysfunction and finally failure. The failure contributes to anger and scapegoating. As long as we scapegoat and lie, the cycle will go on.
Wrong in government is tyranny, which John Locke rightly defined as:
"199. As usurpation is the exercise of power which another hath a right to, so tyranny is the exercise of power beyond right, which nobody can have a right to; and this is making use of the power any one has in his hands, not for the good of those who are under it, but for his own private, separate advantage. When the governor, however entitled, makes not the law, but his will, the rule, and his commands and actions are not directed to the preservation of the properties of his people, but the satisfaction of his own ambition, revenge, covetousness, or any other irregular passion."
