It's not about what the president deserves, but what the people deserve. The founders (after overthrowing one government, forming another, deciding it failed) were tasked with forming a government that can "long endure"... with structuring an office that can both facilitate liberty, but also contend with major enemies foreign (and domestic). The scale of the question is beyond one life or death, but operates on centuries-long timelines. It deals with the equities that face millions of people, not merely the single person holding office.
