Midrash su II Re 24:19

R. Jochanan said again in the name of R. Simon b. Jochai: "What is the meaning of the passage (Jer. 27, 1) In the beginning of the reign of Jehoiakim … The beginning of the reign of Zedekiah. Were there not rulers before them? This signifies that the Holy One, praised be He! was about to return the world to vanity and chaos because of Jehoiakim. But when He looked upon his generation who were righteous, the Lord reconsidered it. And the opposite was the case with Zedekiah. He wanted to destroy the world because of his genaration, but when He looked upon him, He reconsidered it. But is it not written concerning Zedekiah (II Kings 24, 19) And he did that which was evil in the sight of the Lord? [Hence he was wicked.] This is because he should have protested against their deed but did not do so."
