Of course. That's the standard plot of a novel; the hero of the book is not necessarily the one with the most go'sod qualities, but the one who overcomes the most bad qualities in order to become the hero. Read your Campbell. The "hero" of the Lord of the Rings is not Gandalf, or even Aragorn, but Samwise, precisely because he's got the most to overcome -- and does so. More prosaically, the geek becomes a hero by overcoming his fear and standing up to the bullying jock -- and thereby gets the cheerleader.
Not necessarily. This is the modern view; other cultures have had different views. For example, in the Middle Ages Aragorn would have been held up as the hero of LOTR. In the Middle Ages, it's the noble that gets the girl (read El Cid or Beowolf for examples). Tolkein's Silimarilion is much more along those lines.
And we wonder why no one over the mental age of ten likes Rand....
Not quite. Let's look at Rearden for a moment.
His wife was abusive. While she wasn't physically abusive, she certainly was mentally abusive. She constantly insulted, belittled, and undercut everything he did. She constantly went out of her way to hurt him. Yet somehow, Rearden's recognition of the fact that his wife hates and wants to destroy him are held as a sin.
Rearden's brother was
actively working to destroy everything his brother had built, while at the same time enjoying his brother's charity. Yet when Rearden refuses to keep paying his brother (not until AFTER his money had almost all been stolen from him, mind you) it's considered a sin.
I'm confused about the property thing. Who's property did he steal?
The laws were, in the words of Dr. Ferris, not intended to be upheld. And in fact they were impossible to uphold--in order to keep his mills running he had to make a deal with Dannager (to get coal to run them), which is what brought him into court (and into an obviously sham trial). If he DIDN'T get the coal his "customers" would sue him for not giving them the proper amount. Either way, he's screwed; just as the book's antagonists wanted.
His "sociopathic" act was to walk away from everyone. He didn't hurt anyone, didn't even fire a shot when people tried to forceably take over his mills if I recall correctly. He simply decided to stop working. How is that sociopathic?
But you are in the minority. Out of the 5 dozen or so novels I've read, The Fountainhead was easily the worst. Many others have cited an Ayn Rand novel as the worst they've read.
I'm okay with that.

Just because I'm in the minority doesn't necessarily mean I'm wrong; it just means that I'll have to argue my point better.
