It seems, that Death is dead now, was it truely possible for him to kil god ?

Did Death need his ring to access all his powers ?

For Crowley, It was mentioned earlier, that " We don't have him become too powerful off the souls for the sake of the plot, but he could use them more for his advantage if he wanted to."

Castiel became "instable" with all thoses souls in him, would Crowley become instable as well, if he uses too many soules ?
