Tyrion Lannister from Game of Thrones
From the beginning of the Game of Thrones/Song of Ice and Fire series, we can see that Tyrion likes what he likes. He spends his time with women in a less-than-respectable profession and loves to drink as much as any man twice his size. At the beginning of the series, he is rude to many of the other characters and gives off the impression that he is merely a hedonistic slob who cares only about his own well being. However, Tyrion eventually becomes arguably the most ethical character in the series (partially due to author/executive produer George R.R. Martin’s affinity for killing off well-known characters). We learn about his past marriage and his tumultuous relationship with his father. From it, the Tyrion of the present becomes a well-meaning, sympathetic outcast in the midst of Westeros’ greed and corruption.
