Terrible picture of the fate of the wicked

Job 18:1-21
Bildad the Shihite replied: When will you end these speeches? Be sensible, and the we can talk. Why are we regarded as cattle and considered stupid in our sight?
Surely such is the dwelling of an evil man; such is the place of one who knows not God.
Bildad bitterly resents Job's angry rejection of their advice. The arguments is getting personal.
He replies by painting a terrible picture of the fate of the wicked, meant to put Job in his place. But Job is innocent, and Bildad's tirade irrelevant.
Why?
Bildad described much more about the fate of wicked, it meant Job suffering is for his wicked. Actually Job is innocent. Who will know these.
Bildad said about the wicked one is truth, they will ended with terror. But somehow there are righteous man suffer misery, wicked one enjoy their life.
How?
No one knows what he will suffering and why is me? Everything has God's good consideration for he loves me. Avoid the wicked things and do the right things before God's sight.
