inviolable

Can't be destroyed. Will last forever.

Donald Trump crossed an inviolable line when he criticized Khizr Khan's Democratice Convention Speech in which Khizr Khan spoke about his son who sacrificed his life for America.

Inviolate

Free from violation, injury, desecration, or outrage.

At this rate of depredation, I doubt there is a single inviolate spot on Earth.
