If the man has no legal rights in the matter, then he should have no, or at the least reduced, legal responsibility. The argument that "the guy should have thought of these complications before he had sex with her" applies equally to the woman, unless someone wishes to put forth the argument that women are and should be subjugated to the sexual whims of the man. In short, if you're screwin' someone that you aren't willing to have a baby with, then the plan of action for an accidental pregnancy should be discussed beforehand.

It is not entirely uncommon for the man to expressly say that he does not want a child, leading to the woman's intentionally screwing up the birth control in order to have the kid that she wants. It is also not entirely uncommon for the couple to agree to abort unplanned pregnancies, and then the woman changes her mind when she actually gets pregnant. In such cases, 100% of the decision rests with the woman, despite the man's best reasonable efforts at having a contingency plan. If the woman takes 100% of the decision despite earlier agreements, then she should bear 100% of the responsibility. In other words, if we said we would avoid having a baby, and then you decide to have it in spite of that agreement, you shouldn't feel entitled to come running to me for child support.
