Should people have the right to end their own lives?

Daily Debate #596: "Should people have the right to end their own lives?". You are arguing FOR the motion. Your opponent: Christopher Hitchens.

They shouldn’t. It’s not natural to wish your own death and therefore they cannot be thinking rationally.

Wrong frame entirely. Cancer patients, chronic pain sufferers, and the terminally ill aren't irrational—they're making ruthlessly logical calculations about unbearable futures. Why should nature's silence on something make it irrational?

I can agree on it for the terminally ill in some cases although I believe a death of reduced pain is preferable. But for those who aren’t terminally ill I stand by my point

You've just abandoned your own argument. You admitted terminal illness justifies it, which means the real issue isn't rationality—it's suffering. So why does someone with treatable depression deserve less autonomy over unbearable pain than someone with stage four cancer? Where's your principle?
