"After leaving 's company, Korgan Bloodaxe lived in as bloody a fashion as he could manage. He took control of an entire dwarven clan, killing their leader in secret and guiding their revenge to a target of his choosing. He could have lived in luxury, but his thirst for carnage was immeasurable, and he stunned the Realms by pushing deep into the Underdark. The blind fury of the clan took even the dark elves by surprise, but holding territory in the home of the drow is a hopeless proposition. Korgan was last seen burying his axe in the gullet of a high priest of Lolth, laughing as he struck. Dwarven legend immortalized the image, and his bloodlust is now called a crusade. History, it seems, finds more heroes than madmen."
In light of his dialogue with Mazzy, it feels like Korgan *tried* to do what she said. To direct his anger onto a deserving target. But even in doing so, he acted in an evil manner (murdering a clan leader, leading a clan into a war they couldn't win). It also reads as him choosing a death in a way which would earn him the respect in death that he could not earn in life.
Just wanted to share this, because I know that this dialogue option doesn't always pop up so it is very easy to miss. It also highlights the excellent writing from this game.
