Exercise God's right of judgement over others

Psalm 82:1-8
God presides in the great assembly; he gives judgement among the "gods".
How long will you defend the unjust and partiality to the wicked?
They know nothing, they understand nothing. They walk about in darkness; all the foundation of the earth are shaken.
You are "gods"; you are all sons of the Most high. But you will die like mere men; you will fall like every other ruler.
This psalm can be taken as it stands: god takes the gods of the nations to task for their injustice and oppression. This scene recalls Job 1:6. Satan was presented before the Lord.
Psalm can be understood as referring to corruption and injustices in the law-courts: God calling the judges to account. Exercise God's right of judgement over others.
Why?
God presides in great assembly- the final judgement at end of the world.
Man doesn't know the Lord is the almighty. Men are walking in darkness, and doing what they do not know. How pity they are, even they don't know they are gods. People need the gospel to do justice.
John 10:34, Jesus mentioned he is son of God, but the Jews wanted to stone Jesus for blasphemy.  We who believe Jesus is son of the Lord and believe his blood shed on cross is for erase our sin are the sons of God. We are gods. It is noble identity how great we are.
But we all will die as mere men like Jesus, we will transform to another shape with eternal life.
How?
Can I do justice in my living affair? Mercy is needed but do not forsake the justice. Don't afraid the wicked threaten for the Lord is in charge of this world. Aggressively, rescue the weak and needy deliver them from the hand of the wicked.
