i think it's more like "the governor and legislature, who produced and signed this bill, are demonstrably pro-death penalty while simultaneously calling themselves pro-life"
Even if that's true there is no contradiction between being pro-life in the context of abortion and being for the death penalty. You obviously want the death penalty for people who have committed crimes because you think that will curb crime or something. If you were for arbitrarily killing people innocent people and pro-life then I would see a point there.
I am not for the death penalty by the way.
