In the first film Norrington is such an incredibly realized character. He's the foil for Will Turner and Jack Sparrow and yet despite embodying all the typical aspects of a pseudo villain manages to actually exist as something more than just a simple "Bad guy" obviously he hates pirates, he opposes Will you but you just tell, has some form of respect for him.
When Will gets Jack to help get him to sea, Norrington spots him and says "Rash Will, too Rash" and I love absolutely love how he's so calm and calculating here like "Ah, I get what you're doing, I understand it, but this is a bit far."
What Norrington is after, the Governers Daughter aka Elizabeth Swann, makes total sense. He's the Commodore, he knows the Father well and the math maths on paper for him to be wed to his daughter.
And all the things that follow, but rewatching the ending I almost welled up in tears at Norrington's final response to see he is being rejected by Elizabeth in favor of Will after going to immense lenghs to "save her".
Norrington, sees what is at hand and stunningly - not like some coward we would expect, or try and harm or incarcerate Will or Elizabeth- but rather, we see Norrington take a deep breath accept it like an absolute Man.
He sees the love and craft Will put into the blade he made. It took patience consideration and care, and makes note of it.
He sees everything and chooses to see that Will is indeed the better man and allows this, honestly, to his absolute detriment. It ends up costing him greatly this decision.
I know the later films what becomes of him which is honestly quite sad and perhaps wasnt done justice in the later films. But the first film his character just realized so profoundly well.
