Yes, I see that you are indeed in need of some reason. Abortion is wrong because it kills another human being (without the benefit of a trial like those who are executed). This is provable with DNA. Compare the DNA of the mother and the DNA of the child and you'll see I'm right.
Abortion should only be used to save the life of the mother.
BTW, speaking of DNA, I saw an interesting program on TV last night called "I am my own twin". It seems that rarely, very rarely two embryos (very small children) can merge in the womb within a few days of fertilization and become just one person with two sets of DNA. In one case, a male and female fused and had parts of both genitilia.
It seems that you have a firm grasp on reason and a healthy respect for the conditions that gave you life. I agree with you.
