What does the Bible say about the wicked man?

In Psalm 36, the psalmist depicts the wicked man as one who operates without reverence for God, flattering himself and involved in deceitful speech. Verses 1-4 detail the transgressions of the wicked; they do not fear God and engage in mischief, demonstrating their depravity. This echoes the condition of humanity as seen in Genesis 6, where God noted that man's thoughts were evil continually. The depiction serves to highlight the stark contrast between the wicked and God's mercy bestowed upon His chosen people.
