Why would anyone that could prevent pain and suffering allow it?
The WT answer has always been that there is a larger, grander purpose: Universal Sovereignty.
But when you really analyze it, does it make sense? No.
It's like me being upset because the ants outside my house disobey me. According to the Bible narrative as explained by JWs, God is a narcissist that is willing to allow terrible--albeit preventable--things to happen to humans because his reputation is at stake!
After giving this careful consideration for several decades, I've concluded that God--if there is a God--could not possibly be so immature and self-centered. If, on the outside chance, a Supreme Being exists that does indeed have this serious emotional personality disorder, then He is unworthy of my concern, let alone my devotion.
The Bible, particularly as interpreted by JWs, paints Jehovah as a petty tyrant given to capricious, unpredictable temper tantrums not unlike an abusive control-freak.
I'm not having any of that myself.
