IS it a contradiction? I don't agree with the death penalty or anti-abortion position, but I don't see some essential link between either position. You can hold two different beliefs about two different things is how come.
Sure, but OP didn't ask, 'How can people call themselves pro-life but are be for the death penalty?' I'm not one to hang onto whatever catch phrases or name a movement lands with. Should* I expect the land back movement to, say, lay down on the ground as a for of protest? 'BUT LAND BACK IS IN THE NAAAAAAAME'. Do we think defund the police want there to be nobody to apprehend, say, right-wing terrorists?
