Count Olaf is a vile, and terrible man. A man whose acquaintance I have had the misfortune to endure several times in my life. He has planned and attampted to execute, several plots to gain the Baudelaire fortune, and the Baudelaires themselves. The word "Execute" here means: "to carry out or put into effect a plan or course of action". However, this word, like many others, may have to meanings. The word "Execute" here, also means: "To carry out a sentance of death upon a condemned person."
So when I say, "Attempted to Execute several plots to gain the Baudelaire fortune, and the Baudelaires themselves." I mean that Count Olaf has not only attempted to steal the enormous fortune belonging to the Baudelaire orphans, but he has also attempted to kill the Baudelaires themselves.

His voice has haunted my dreams for many months and as such, In my attempts to bring the history of the Baudelaire orphans to the public, I am looking for a voice as accurate to the real thing. He speaks in a wheezy growl, like a growling, wounded animal. As if sandpaper, a tool normally used by carpenters to make wood smooth and soft, had been scraped across his vocal chords.

However, if you wish to take your own spin on the character, feel free... I guess
Count Olaf is one of the main characters, and as such has many lines. Speak with malice and "Iniquistiousness", a word which here means, "Absence of moral or spiritual values or an unjust act"
