Sin produced death in me through what was good

Romans 7:7-13
For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. So then the law is holy, and the commandment is holy, righteous and good.
Did that which is good, then, become death to me? By no means! But in order that sin might be recognized as sin, it produced death in me through what was good (但罪藉著那良善的叫我死，就顯出真是罪),so that through the commandment sin might become utterly sinful.
Not that there is anything wrong with God's law in itself. It is wholly good. But by its very existence it creates an awareness of sin.
Why?
Law is good , holy and righteous.
I wound not have known what sin was except through the law. Law let me know what is right and wrong.
It is the sin inside me control, deceive me to sin.
How?
Knowing the law, conquer the sin through Jesus Christ.
