Why was Roe v. wade a controversal case?

Curious why it was a controversal case? I have an answer

Explanation:Roe v. Wade was a 1973 landmark decision by the US Supreme Court. The court ruled that a state law that banned abortions (except to save the life of the mother) was unconstitutional. The ruling made abortion legal in many circumstances. Roe v. Wade, 410 U. S. 113 (1973), was a landmark decision of the U. S. Supreme Court in which the Court ruled that the Constitution of the United States protects a pregnant woman's liberty to choose to have an abortion without excessive government restriction.
