Will I be sinful if I restore the deleted channels on my father's satellite dish after he strongly ordered me to do so?

"Removing an evil is not legislated if it leads to a greater evil or alienates the one being called to righteousness. If the father does not watch prohibited content through the channels, then obedience to him is obligatory, and it is not permissible to remove the device because it does not belong to you. However, if he does watch prohibited content, then it is not permissible for you to return it, and you must explain to him that refraining from returning it is out of fear for him and yourself from God's wrath. It is not permissible to cooperate in sin and aggression except under duress that is considered valid in Islamic law."
