Why the real villain in "The Social Network" is Mark Zuckerburg

After watching "The Social Network" I have decided the villain is none other than Mark Zuckerburg. All though the real life events portrayed in the film may be exaggerated, it appears here that he is the villain. One reason for this is him publicly humiliating his ex-girlfriend Erica Albright on the internet by making a long insulting blog post about her.  Another is him making The Facebook behind the Winklevoss twins backs after he agreed to help them as a programmer for their website called "The Harvard Connection" which was a dating website exclusively for Harvard students, and very similar to Mark's idea for "The Facebook". Mark also tricks Eduardo Saverin into signing away the majority of his share in the company by hiding in a contract he had him sign that wasn't explained completely basically exploiting Eduardo's trust . Zuckerburg comes across as emotionless and cold in the film which  makes it harder to empathize with him, and easier to place him in the role of the villain.
