The Psalmist is carefully teaching the righteous man about the reasonable law of moral nature in the moral axioms.  The wicked borrow reality and use it to do bad things. Anyone who illegally applies the law of God turns out to be a persistent fool.

 A person who does bad things like hurting people can use the law to hide their bad actions.

 The moral law that accurately describes the eternal beauty and elegant symmetry of divine creation, judges the wicked who overturns Gods order.

When they break the law, they end up in a situation that is against their own interests.

God's saints live in a kingdom of divine unity and symmetry, while the wicked live in an imaginary world they created.

7 16The trouble he causes turns against himself; his violence will fall on his  head.17 I will thank the Lord for his righteousness 

 and I will sing praises in the name of the  Most High. “The psalmist carefully teaches the correct pronunciation of the reasonable law of moral nature in  moral axioms. But the wicked borrow the law from all reality and use it to promote violence. Anyone who illegally uses God's law turns out to be a stubborn fool. The moral law which accurately describes the eternal beauty and elegant symmetry of divine creation accurately judges the wicked who overthrow the order of God. The trap set for the righteous to remain only their own downfall. Inevitably, they fall into their own made-up description of an incorrect use of the law. God pronounces his particular glory in the fundamental axioms. A professional enjoys extraordinary experiences of praise and glory. The saints of God undoubtedly live in an eternal realm of divine unity and elegant symmetry while the wicked inevitably suffer in a make-believe world they conceive of.
