Law is like a red light, its functions are meant for the benefits of the user.
But sin turns the goodness of law into somethings which works against us.

12Therefore do not let sin reign in your mortal body so that you obey its evil desires.
13Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness.
14For sin shall not be your master, because you are not under law, but under grace.
Romans 6
1 Do you not know, brothers—for I am speaking to men who know the law—that the law has authority over a man only as long as he lives?
2 For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law of marriage.
3 So then, if she marries another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress, even though she marries another man.

4 So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God.
5 For when we were controlled by the sinful nature,[a] the sinful passions aroused by the law were at work in our bodies, so that we bore fruit for death.
6 But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code. Romans 7
