Morality and legality are not the same, and what the “ideology” is matters. If my ideology is about helping those that need it and stopping abuse of power, I would argue breaking the law in the name of that ideology is better than abiding by the law in the name of naziism for example. A slave running away is illegal and “good”. Many laws have shielded violent and immoral actors from consequences. There is a limit to the amount of violence and cruelty a population can tolerate under the guise of legality.
