Diane's ambition

There's a great storyline in season 5 where Diane wants to become a judge after Peter's offer. In an interview with a journalist, she tells the whole country that Will stole money from a client. In essence, she humiliated and betrayed the man with whom she had worked for many years. When nothing worked out, Diane came to make peace as if nothing had happened. What if she became a judge? Then she wouldn't have remembered Will and never apologized. She would have just stepped over it and moved on up the career ladder.
Will, of course, is not a gift himself, but Diane’s act was vile. Or are there no friends in business?
And what is your opinion about Diane Lockhart?
