Why did the noble verse, "Say: You will not be questioned about what we committed, nor will we be questioned about what you do," describe the evil deeds of Muslims as "committing a crime" while describing the deeds of disbelievers as merely "doing"?

The verse demonstrates the Quran's eloquence in debate, where the accusation is directed at the speaker rather than the opponent, to ensure the opponent continues to listen and accept the truth, as stated in His Almighty's saying: (AND INDEED, EITHER WE OR YOU ARE ON GUIDANCE OR IN OBVIOUS ERROR). This is from the etiquette of debate, which encourages the opponent to continue the discussion and acknowledge the fairness of the Sharia.
