The Ethical Engineer / Deathworld II is a science fiction novel by Harry Harrison first published in 1963, under the name The Ethical Engineer.

In Deathworld II, Jason is kidnapped by the self-righteous Mikah, who is determined to bring him back to the planet Cassylia, ostensibly to be tried for his various crimes but really.

He forces a crash-landing on a planet where the human population has regressed. The technology is extremely primitive and knowledge is split up among many small clans, each one jealously monopolizing what it knows.

Jason uses his ingenuity to survive, trading his knowledge for protection and power in one of these clans. He eventually reaches the clan who has the knowledge of electricity and signals his location to a spaceship piloted by his Pyrran girlfriend, Meta.

”That mores is strictly a matter of local custom cannot be denied. But that ethics is pure opinion also...? Maybe there are times for murder, and theft and slavery....”
