The courtroom death of former Egyptian President Mohamed Morsi on Monday is a stain on his nation’s justice system. But history won’t regard Morsi kindly. He wasted an opportunity to lead.

That doesn’t make his death less concerning, of course. Morsi’s family suggest he was given inadequate medical support in prison and had been suffering from illnesses including diabetes and high blood pressure. The senior Muslim Brotherhood leader was also denied regular access to independent observers. Morsi’s supporters will react furiously to his demise and deserve an explanation for his death.
