Yes. Also, I liked how the ties between Leon and Matthias form the root connection between Belmont and Dracula. That both Leon and Matthias were holy warriors, fighting in God's name, but Matthias would turn against God when tragedy struck, and Leon did not. But really, both are almost different sides of the same coin. Leon just didn't choose to let his sorrow overwhelm him and cause him to curse God when he had to kill Sara. But yeah, I actually liked that a lot. It made the connections run deep. You start to see it as two good friends, "brothers in arms", that go through similar tragedies, and wind up coming to a fork in the road and both take different paths that, somewhere down the line, will cross(of course, symbolically, since it's the Leon's descendants that meet Dracula).
Besides, I never seen Matthias Dracula as NOT being a "surpreme evil being of pure evil". He DOES eventually become that later on(after Lisa is killed). He just doesn't start off that way. But yeah, after years of darkness, seeking to wipe out humanity, Matthias, who is now Dracula, IS the Dark Lord, the ruler of the Demon Castle. Just because he started his life as Matthias doesn't make that part of him any different. He was still causing great death and chaos through Europe during the time of CVIII. He's still the heartless, cruel vampire lord that all the townsfolk fear. That never changes.
