It can be a necessary evil (don't get too hung up on that word evil, I'm just using the expression loosely). That is, given the way our society is right now, I can see why it's necessary. In a perfect world, it would be unnecessary.
My main issue is that people are unwilling to call it what it is: killing a potential baby. And my issues with the prochoice side have always surrounded that, but in every discussion I've had about it, they try to make it about a womans rights issue, which it is, but it is ALSO a baby's rights issue too. I don't believe in the arguements that say it's not a person or that it's not alive. And that is not up for debate IMO. It is a person and it is alive. Period.
