If your condom breaks, you never intended to have a baby, thus not committed.
If you find out you are pregnant a few weeks later after all and haven’t committed to having the baby, you consider your options and aport it if you don’t want to commit.
If you find out you want to keep it, you don’t abort it and you have now made a commitment, and can’t abort it if you change your minds again a few months or years later.

Sure, but commitments don’t ultimately change biology. After fertilization, you’re making the choice to snuff out a life or not.
