God isn't Unfair, people are
Someone correct me if I'm wrong, but it doesn't appear that this forum is related to any particular piece of literature, except maybe the Bible and Quran.
I used to think God was fair by definition, so whatever bad thing came my way was either training material because he liked me, or punishment because I'd been bad. Having been raised Catholic, in addition to other formative events, I believed the latter more often than the former.
After leaving the One True Church, and spending a decade in various forms of evangelical fundamentalism, which, it turns out are also One True Churches, I finally concluded that there is no God.
This began to happen when, as I was reading the story of David and Bathsheba, it was suddenly transformed before my eyes.
David, King of Israel, is up on his roof and spots Bathsheba bathing on another roof. He exercises his kingly prerogative, summons her to his chambers, then sends her home. Pregnant, it turns out. He brings husband Uriah home from the war for some unscheduled leave, hoping he'll muddy the tracks, but Uriah is a man of honor. He won't indulge himself while his comrades in arms are suffering on the front. Frustrated, David sends him back to the front, and instructs Uriah's commander to take the men into battle, then withdraw, leaving Uriah alone in the thick of it. This works. With Uriah dead David marries Bathsheba. At this point, God decides He can't condone all this treachery.
He does the only reasonable thing, under the circumstances. He executes the baby.
Getting on in years, David decides he needs someone to keep him warm at night and sends his gophers out to find that special someone. You'd think Mical and Bathsheba could keep things plenty warm enough for him, but he brings in Abishag the Shunammite, probably all of 15 years old, to take the chill off. Finally he dies, old and full years, and God's favorite guy, after Abraham.
So David and his obedient Army Officer get off scot-free, while the baby and Uriah (and Abishag, for that matter) get punished.
I realized then that God was no better than a common CEO. I lost interest in furthering His ends. After that it was a few short steps to realizing He didn't exist.
