My question mostly stems from the existence of such word as infamous which perfectly solves the problem when you want to talk about someone being famous but in a bad way. When you want to address actions of a criminal or a terrorist saying that they were efficient in their actions sounds wrong, that's why I'm curious is there a word similar to infamous but in regards to efficiency?

Sentence example: The perpetrator ended up being much more _____ than an average terrorist

    I don't think so and I don't think it's needed. Example (en.wikiquote.org/wiki/Nazism): "[Nazi] Germany is showing to the world how efficiently violence can be worked when it is not hampered by any hypocrisy or weakness masquerading as humanitarianism. It is also showing how hideous, terrible and terrifying it looks in its nakedness." Mahatma Gandhi in Zionism and Anti-Semitism (November 1938), as quoted in The Gandhi Reader: A Sourcebook of His Life and Writings, p. 319 Dec 25, 2017 at 14:53

  • I suggest your Question is based on a misunderstanding - and a very important one - of efficiency. Have you heard said Once the rockets are up, who care's where they come down? That's not my department, said Wernher von Braun? Efficiency has nothing to do with right or wrong, nor could it ever. Dec 29, 2017 at 1:12

You might use calculated, according to Cambridge Dictionary:

planned or arranged in order to produce a particular effect

An example sentence by Politico:

In Charlottesville on Saturday, I witnessed a brutal, calculated act of terror.

In your sentence:

The perpetrator ended up being much more calculated than an average terrorist.
