Do characters' need flaws?

Yes characters do need flaws to portray true beauty. People all have different views and opinions on what beauty is. When one reads a magazine and thinks wow she is beautiful or extremely attractive, they are not really sticking a name to that particular person, since the picture in the magazine has been edited to a single pixel to have it ''plastic'' perfect. In magazines they want to sell you something, either it be the magazine itself or a product. Each photo is critiqued to simplistic perfection. This is not true beauty, since you cannot find a beautiful person based on a picture in a magazine or a published article. I am not insisting that the person in the photograph is not beautiful, because the person may be. A character has to be realistic, since everyone has flaws, even if it is the smallest mark on a visible spot. Everyone is born with a special feature that may or may not be unique to them, but it is still a flaw that is marked as human.
