In like manner, I believe that reactors should be designed such that an earthquake of any magnitude could not destroy the reactor or its containment shell, further that if the reactor core was to start to melt down, the melt down itself would shut the reactor down and, at the very worst, the reactor would entomb itself with no potential release of radiation into the environment.

If she had been diagnosed with pancreatic cancer, fought through rounds of chemo and radiation to no avail, and decided against a bone marrow transplant (which, in this hypothetical situation, which reflects the vast majority of real cases, would more likely kill her than enable a cure) she would be honored and remembered as noble, virtuous and brave.
