One thing that JW's teach that I can't abide by is that God allows bad things to happen so that he can vindicate his name after Satan challenged him in the garden of eden. If you tell me that God is loving, than you cannot also state that he would allow an earthful of people to suffer starvation, cancer, war and countless other atrocities simply so that he feels better about being challenged. He's God -right? It's logical to me, that if challenged he would have destroyed Satan and protected his creation. I simply could not ever watch my children suffer -even if they did something to hurt me. So these two teachings coming from the same organization are contradictory.
This teaching alone, is part of why I became agnostic.
