I believe exactly what Paul said, "God bound all men over to disobedience..." Why don't you?
What text are you referring and what translation are you using?
And if God didn't "design the consequences" of sin, who did? Satan? Mother Nature? Where did God go while that was being decided? On vacation?
This is like saying God must have designed unrighteousness! Have you ever considered that unrighteousness does not have to be designed but rather is the absense of righteousness or all that is opposite to or anti-righteousness??? Sin does not have to be designed but is the absence of or opposite to obedience?
God is holy and righteous but God did not design holiness and righteousness and neither does he design unholiness and unrighteousness (sin) as they are merely the natural opposites to what God is. God is life but God did not have to design life and neither does he design death as it is merely the absence of life and its natural opposite.
Certainly hell was designed by God as a place of punishment for fallen angels. However, the consequences of sin in regard to death and all it entails are natural and necessary consequences of opposing life.
This is like asking who designed darkness when darkness is merely the absence of light.
