I apologize for my delayed response to you.
I think it is important to look at the context that has motivated you to wonder if you are this person. This may give you some clues as to whether you are this person.
Additionally, I think it is important for everyone to sincerely question whether they are like the people described in this article, and to perhaps take ownership of some of your more destructive behaviors.
I think we all, to some degree, display some of these characteristics, at different points in life, or within different contexts. If this is a primary orientation for you, independent of context, perhaps you could gently acknowledge what you need to change, and begin to be more accountable in shifting these elements of your self.
If you have more specific questions you want to follow-up with, pertaining to this article, please feel free to write. I am sure you are not the only one who might benefit from this comment thread and series of questions and answers.
