Theological Wordbook of the Old Testament: ra in Isaiah 45:7 denotes calamity, not moral evil

The Theological Wordbook of the Old Testament states that ra denotes physical injury (Jeremiah 39:12) or times of distress (Amos 6:3), and specifically for Isaiah 45:7 renders it "I bring prosperity and create disaster." The TWOT notes that ra most commonly denotes unethical or immoral activity but acknowledges Isaiah 45:7 as a distinct usage meaning hardship, bad times, times of distress.
