Otherwise, Glamorgin the Terrible is cunning and ruthless. He shows no mercy to guards or nobles, unless they can fetch a good ransom.

If said guards or nobles were begging for mercy, I can easily see the following coming out of the character you described.

"The Gods show mercy. I don't."

"I'll be the son of a sea devil. And if you ask my men they'll tell you true."

"To you it's money. To me it is the ale and ho's. Put up or shut up."

This ones quite long and could do with some tweaking:

If you don't stop ye yammering, I'm gunna rip of ye arm, and feed it to you through your nose.
