What does Habakkuk 1:13 mean?

Your eyes are too pure to look at evil; you can't tolerate wrongdoing. So why do you put up with traitors? Why are you silent while the wicked swallow up people more righteous than themselves? Habakkuk 1:13 - Modern Text Bible

(Habakkuk struggles with the idea that God would use a nation even more wicked than Judah to punish His own people, questioning how this fits with God's justice.)
