Neither, because the punishment of criminals and the ethics of human reproduction are not the same thing.
Exactly! There is no "double standard".
If someone was for the death penalty, but didn't want their brother on death row to be put to death, that might be a contradiction. If someone was against the death penalty, until their sister was murdered, that might be a contradiction.
Likewise, if someone was against abortion, until they got unintentionally pregnant, there is a contradiction. I can't think of a similar one for Pro-Choice people, sorry.
I sometimes think it odd that people can be Pro-Life but not against war or the death penalty, or that people can be Pro-Choice but against the death penalty. But I don't think there is a contradiction, because these are separate matters, and people are complex.
I have Pro-Choice vegan friends that would say that there is a contradiction between being Pro-Life but still eating meat. I have Pro-Life vegetarian friends who say there is a contradiction between not eating meat but being Pro-Choice. But I feel that how one feels about legal, elective abortion and how one feels about eating meat, and how one feels about the death penalty, and how one feels about war; are different things, with little in common.
I am Pro-Choice because I believe that even pregnant women should retain control over their own bodies, including the right to deny use of their bodies to any other humans. I am against the death penalty because I worry that innocent people might get convicted, and there is no way to resurrect people if the State is wrong; as well as I believe it to be cruel and unusual punishment (due to the immense pain cause by every method since the guillotine - and hanging if it is done properly). I am against wars that are unjust (but feel that some wars, like WWII were necessary). I eat meat, because humans are naturally omnivorous. I see no contradictions in feeling all of these things, because they all have to do with different subjects, and they all are logical arguments for why I feel the way I do.
I do notice that most people seem to feel that there is only a contradiction when someone hold the opposite opinion than them on the two topics (abortion and the death penalty), but no one sees a contradiction in their own opinion on the two matters.
