That's what machiavellian distills into - cold pragmatism and disregard of morality. So his turn from okay guy that wanted his family to stop with illegal shit into someone much worse than his father was portrays it perfectly.
I saw this movie at a press screening back then. I had to go to the bathroom from the very beginning, but I couldn't because it was so damn thrilling. My bladder still hurts today when I think about it.
There is a movie called "The Godfather", which depicts a fictional war between mafia families in the US. In the film, there is an older generation that operates on a kind of respect system, and attempt to keep each other reasonably balanced, in both power and money terms. A drug dealer enters the picture, and attempts to murder Michael Carleone's father (who is the Godfather). In response, Michael plans to meet the drug dealer and a corrupt police captain, sneak a gun into the meeting, and shoot them both. That plan works.
Later, the Godfather dies, Michael takes over as the head of the Carleone family, and plans assassinations of all of the older generation of every other family in a coordinated attack, during his father's funeral. That plan works too, leaving him as the most powerful survivor.
Anon once heard someone’s opinions about a movie character, decided it must be so. Having a mind locked up tighter’n Fort Knox if it were located deep inside Area 51, he was badly disappointed when the character didn’t match the wild expectations he set for himself.
The expectations were set by someone else. For me, the memes hyped the hell out of Khan and one day I decided to watch the trek movies. Yeah, Khan did not live up to the hype. I had seen much more interesting scifi villains and space battles by then.
