Complex systems don't pop out of thin air.

The US form of government is highly based on the existing British one and the British King had the ability to pardon and so that was copied over.

I do think it makes a lot of sense to do things like mass-pardon people for things that are no longer crimes (i.e. weed legalization) but I really don't see how singling out cases is correct since the supreme court already can do that.
