Jews who believe that abortion may be right are referred to as Pro-Choice as they believe that the mother should be allowed to decide whether or not she wants an abortion.
Some Jews who believe that, in some circumstances, abortion is right are referred to as Relative Moralists as their view relies on the situation.
S.O.W. - "For as long as it did not come out into the world, it is not called a living thing and it is allowed to take its life in order to save the mother." - Rashi
