I also believe it is wrong except in cases of rape, incest, or if it is a danger to the mother. If the woman didn't have a choice to have sex to get pregnant at that point she shouldn't have to be responsible if she doesn't want to. That's not to say that good cannot come from that child, but the woman just may never forget about it.
In this town I live in there is a girl who is under 20 (I don't recall her exact age) but she is now pregnant for the 6th time. She has had 3 miscarriages and 2 of the kids were taken from her. This is why abortion is wrong. It's not a method of birth control for people who are to stupid and irresponsible to put a condom on, use birth control or something else. If you are responsible enough to take the risk, then man or woman up and take the responsibility for the child you helped produce and stop crying about it. At the very least, have the child and give it up for adoption. There are people out there would do anything to be able to have a child.
