Because abortion is termination of
pregnancy, not termination of
life.
And it's nice to know that you're OK with slavery under certain circumstances.
As for "the mother's choice," I take it then that you'd be OK with abortion in the event of rape? (And let's not forget that your Bible commands abortion not in that case, but in the event that your wife cheats on you--which would, at least in some cases, be consensual on her part and hence not rape--and that it's God who ultimately makes the determination as to whether an abortion is warranted. See Numbers 5:11-28.)
As for the death penalty, what that does, more often than not, is create martyrs and thus exacerbate the problem, where life imprisonment generally leads to people forgetting about the person in question.
I also noticed that you haven't addressed my points about organ donors (we don't take organs from dead people unless they consented in life) or Savita Halappanavar.
I do not accord
anyone the right to violate another's bodily autonomy. That is why I support the unfettered right for women to choose either to carry a pregnancy to term or to terminate that pregnancy as they wish. Furthermore, I support access to all forms of contraception, mandatory comprehensive sex education so that people--particularly libidinous teenagers--know how to avoid unintentional pregnancies (consider that states with abstinence-only sex education, like Mississippi and Texas, are among the top states in the US for teen pregnancy, repeat teen pregnancy, and teen abortion, while states with comprehensive sex education, like New Hampshire, rank near the bottom of all those categories), social supports for women and families with young children, particularly single mothers and low-income families, and extensive maternity and paternity leave so that young children can properly bond with their parents. All of these policies reduce abortion rates.
But I will not--will never--support violations of someone's bodily autonomy, and I will never force a woman to seek dangerous, possibly fatal, means of ending a pregnancy she does not want.

EDIT: I also support some form of single-payer health insurance.
The average cost of giving birth in the US is, as I have noted previously, over US$38,000. That alone would incentivize women to seek an abortion, simply due to its unaffordability. (Consider that, depending on your source, at the low end
almost half of US families cannot afford an unexpected $500 expense. How do you expect them to afford $38,000 given only seven or eight months' lead time--never mind what happens if the child is premature?) By contrast, when Catherine, Duchess of Cambridge gave birth to Princess Charlotte, her second child, you can be sure that she had the absolute best care possibly available, and it cost US$19,000. For twice that I'd expect something absolutely, jaw-droppingly amazing, but I doubt the average mother giving birth in the US gets anything nearly as lavish as the Duchess had.
