Hey, if I have a cancerous tumor in my body that I don't want, I'm getting it removed. Same thing if I have a fetus I don't want, it's going bye bye (note, i'm a guy so the second won't be happening I really really hope). Tumor is a living mass of cells, fetus is a mass of living cells. You can say that the fetus has the potential to form into a human, perhaps I have some kind of rare cancer that if left would develop into a full other person. Fuck potentials, think of what is. And in the case of an unwanted pregnancy, what is is that that shit's gotta go however it has to get gone.
