Worst thing Chuck has ever done?

For me definitely sabotaging Dan's second book.

It may be because it's also my dream to become a writer but I seriously can't like him after this. A book is a huge deal, we put our best ideas in them, the best and worst side of us, our experiences and our imagination.

Seriously how is Chuck not cancelled, I can barely find anything likable about him (the only thing I like is his relationship with his dog, and he didn't even want him at the beginning)
