All writers, in all viewpoints, must choose which information and scenes will be presented, and in which order. In that sense, the author is always represented as a point of view in a work of fiction. His hand can always be detected by the discerning.
In one sense, every character you create will be yourself. You've never murdered, but your murderer's rage will be drawn from memories of your own extreme anger. Your love scenes will contain hints of your own past kisses and sweet moments.
