California has just become the fifth state to legalize so-called “aid in dying.” Under the law, certain terminally ill California residents can elect to end their lives with the help of a doctor’s prescription. Following an emotionally-charged debate, Gov. Jerry Brown signed the bill into law Monday, writing, “in the end, I was left to reflect on what I would want in the face of my own death.” For many supporters, this represents a pivotal moment for an issue that’s been gaining steam across the U.S. But for critics, California’s decision takes the national conversation about end-of-life options in the wrong direction. We hear both sides, and what the California law could mean for other states.
