Well, the hypocrisy is equal when it comes to the people who are pro-life and for the death penalty. It is odd that one side isn't pro-life and anti-death penalty and the other pro-choice and pro-death penalty (not that those people don't exist--I'm assuming you're one of them, Bien?--that's just not how the usual polarity plays out).
I think what makes the issues different is that when it comes to abortion, it is one person making a decision that directly effects that person (of course that person's family is involved and so is the father). When someone is sentenced to death, it's a group of 12 people with no connection to the accused deciding the fate of that person on evidence that is too often dubious. Whether this person lives or dies doesn't affect any one person in such an impact fil way as a new child will for a parent.
In essence, what I guess I'm trying to say is that it's kind dumb to say if you're for (or against) one, you should be for (or against) the other. They are two completely different issues with completely different contexts.
