M. Puzo, the Godfather:
What annoyed Clemenza was that the execution had to be "public". That is, the body was to be found. He would have much preffered having it disappear. ([...]) But it had to be public so that embryo traitors would be frightened and the enenmy warned that the Corleone Family had by no means gone stupid or soft.
I'm confused by the word embryo and the Corleone Family had by no means gone stupid or soft. Couldn't you explain the meanings here?
