11 He says to himself, “God has forgotten; he has hidden his face and will never see.” 12 Rise up, Yahveh God! Lift up your hand. Do not forget the miserable ones. 13 Why has the wicked person despised God? He says to himself, “You will not follow it up.”
The one who exploits the poor and weak has convinced himself that God is not watching, and will never follow up the crime with justice. That mindset is a trap. God sees every teardrop and drop of blood. He remembers it all and will not forget our actions. It is actually better for the wicked to be brought to justice in this age, rather than go their whole lives thinking that there is no accounting for sin. After death there is no repentance. Only judgment day upon the return of Christ.
