Huh, I just thought of an interesting parallel. In Mass Effect 2, when you first meet Mordin, you're helping him to fix a machine and put a cure for a disease in the air. Then later, in Mass Effect 3, when you say goodbye to Mordin, you're again helping him to fix a machine and put a cure for a disease in the air. I'm not sure if these paralells were intentional, but given the usage of the Carnifex in that scene, it's interesting to think about.
Such parallels are probably intended, but not necessarily with a deeper meaning than just a nice 360° in the story, just like that Hero's Journey diagramm or a classic story structure; you come back to the place you began your journey.
But it could be more, though I don't see to what purpose.
But nice noticing it!
