I'm for Abortion, because if they don't have the heart in them to become parents... or aren't financial or fit enough to look after a child, then the best option is Abortion.
But even though it's probably true that it's the woman's choice, I can't bring myself to admit, especially when in a relationship between a man and a woman. In that case, I believe it's the choice of both parties. If my girlfriend was to be pregnant, I want my opinion heard and I certainly want it talked out before she does anything without me knowing. After all, I'm the one who impregnate her[intentionally or unintentionally], so it should be a part of my responsibility. I'm a person who would love to have a family in the near-future, though I'm not stupid enough to start one whilst unqualified for jobs
If the man fucks off after sex or rapes her, then the woman automatically have all the right to the baby, including his/her fate.
