ewq,
One of your major problems with Job 9:23 is that you have not done adequate research to understand its meaning. To understand its meaning, we need to know that according to Job 9:1, this is Job answering.
Job 9:23 reads in several different translations:
New International Version
When a scourge brings sudden death, he mocks the despair of the innocent.
New Living Translation
When a plague sweeps through, he laughs at the death of the innocent.
English Standard Version
When disaster brings sudden death, he mocks at the calamity of the innocent.
New American Standard Bible
"If the scourge kills suddenly, He mocks the despair of the innocent.
King James Bible
If the scourge slay suddenly, he will laugh at the trial of the innocent.
Holman Christian Standard Bible
When disaster brings sudden death, He mocks the despair of the innocent.
International Standard Version
If a calamity causes sudden death, he'll mock at the despair of the innocent.
NET Bible
If a scourge brings sudden death, he mocks at the despair of the innocent.
Douay-Rheims Bible
If he scourge, let him kill at once, and not laugh at the pains of the innocent.
English Revised Version
If the scourge slay suddenly, he will mock at the trial of the innocent.
Revised Standard Version
When disaster brings sudden death, he mocks at the calamity of the innocent.
New Revised Standard Version
When disaster brings sudden death, he mocks at the calamity of the innocent.
The word translated as 'calamity' in ESV, RSV and NRSV has the footnote, 'The meaning of the Hebrew word is uncertain'. You are basing your understanding of God laughing on a word whose meaning is uncertain. i think you are on the wrong side of the debate.
Before you tear strips off God's inerrant Word, I recommend you take a breather and examine the text as it does not seem to say what you want it to mean.
Good studying!
