In the end of the book 1984 by George Orwell have the main characters Winston and Julia been broken down mentally by the treatment they were given in Room No. 101?

Finished reading the Fountainhead by Ayn Rand.
A book that made me think about objectivism a bit but I finally settled down on the fact that no one philosophy can perfectly work in unison with our complex minds.
Also found the book to be quite lengthy and some things didn't make sense like the fact that Howard Roark was acquitted from court in the end.
