Thus it appears that man cannot have a true notion of sin but by means of the law of God….The law, therefore, is the grand instrument in the hands of a faithful minister, to alarm and awaken sinners; and he may safely show that every sinner is under the law, and consequently under the curse, who has not fled for refuge to the hope held out by the Gospel: for, in this sense also, Jesus Christ is the End of the Law for justification to them that believe. (Dr. Adam Clarke)

The commandment - That is, every branch of the law.  Is holy, and just, and good - It springs from, and partakes of, the holy nature of God; it is every way just and right in itself; it is designed wholly for the good of man. (John Wesley)

Deceived me - The word used here properly means to lead or seduce from the right way; and then to deceive, solicit to sin, cause to err from the way of virtue, Romans 16:18; 1 Corinthians 3:18; 2 Corinthians 11:3, “The serpent beguiled Eve through his subtlety,” 2 Thessalonians 2:3. (Dr. Albert Barnes)

"Paul’s focus in these verses was not on whether the person is regenerate or unregenerate.  The power of sin is present in any person who tries to keep the law on his own. (Tyndale concise Bible commentary)

He sets himself before us as an example, in whom all men may behold, first what they are by nature before they earnestly think upon the law of God: that is, stupid, and prone to sin and wickedness, without any true sense and feeling of sin, and second what manner of persons they become, when their conscience is reproved by the testimony of the Law, that is, stubborn and more inflamed with the desire for sin than they ever were before. (Geneva Bible Translation Notes)

Though sin is in us, yet it is not known as sin, neither does it rage in the same way that it rages after the law is known. (Geneva Bible Translation Notes)

Paul’s point here is that the law reveals what sin is and must be distinguished from the sin itself.  The law is not sin (5:20; 7:4–6), just as light is not that which it illuminates.  (Tyndale concise Bible commentary)

But now we are delivered from the law - We, who have believed in Christ Jesus, are delivered from that yoke by which we were bound, which sentenced every transgressor to perdition, but provided no pardon even for the penitent, and no sanctification for those who are weary of their inbred corruptions. (Dr. Adam Clarke)

The illustration in this verse and the following is designed to show more at length the effect of the Law, whenever and wherever applied; whether in a state of nature or of grace.  It was always the same.  It was the occasion of agitation and conflict in a man’s own mind.  This was true when a sinner was under conviction; and it was true when a man was a Christian.  In all circumstances where the Law was applied to the corrupt mind of man, it produced this agitation and conflict. (Dr. Albert Barnes)

An application of the similitude of marriage. "So", he says, "it is the same with us: for now we are joined to the Spirit, as it were to the second husband, by whom we must bring forth new children: we are dead with regard to the first husband, but with regard to the latter, we are as it were raised from the dead." (Geneva Bible Translation Notes)

Another point remained to be treated of by the apostle — the effect of this last doctrine upon the question of the law.  The Christian, or, to say better, the believer, has part in Christ as a Christ who has died, and lives to God, Christ being raised from the dead through Him.  What is the force of this truth with regard to the law (for the law has only power over a man so long as he lives)?  Being then dead, it has no longer any hold upon him.  This is our position with regard to the law.  Does that weaken its authority?  No. For we say that Christ has died, and so have we therefore; but the law no longer applies to one that is dead. (Dr. John Darby)

This is a simple illustration and one should not engage in puerile fantasy when gleaning its very upfront meaning—that death dissolves all those things that bind us to the law in life.
