This is the biggest piece of Randish poppycock
Don't get excited, take your time. Please reread what you criticized. You seem to have missed the most important phrase, "...their meaning and their costs...." You may totally disagree with everything Ayn Rand wrote or said, but she was always careful about what she said. None of what you implied is true, if you include the phrase you apparently missed.
Since you apparently do not believe good and evil can be determined using the only faculty God has given us with which to understand the truth, what faculty do you propose one uses to determine what is true?

You assume a truth and a God. So do I. God gave us truth with regard to good and evil. We need to be rational in living our lives according to that morality. But that morality did not emanate from the use of reason. If so, all rational people would be good. They are not. Many rational people (Dr. Moriarity, the Grinch, Lex Luther, Stalin, Hitler, Pol Pot) are perfectly evil.
