No, God does not delight in punishing sinners. But God does desire to demonstrate his wrath, power, and justice. He is glorified when his justice is upheld.
[11] Say to them, As I live, declares the Lord God, I have no pleasure in the death of the wicked, but that the wicked turn from his way and live; turn back, turn back from your evil ways, for why will you die, O house of Israel? Ezekiel 33:11
[32] For I have no pleasure in the death of anyone, declares the Lord God; so turn, and live." Ezekiel 18:32
[22] What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction Romans 9:22
