He probably does think about that since thats what the caused the split between the Geth and the Quarians. And I always thought it'd be kinda cute if Legion actually had emotions. like you said, they kind of hinted at it with Shepard's Armor and things like that
There's actually a princess bride reference in game.....have Thane in your squad when you meet the "biotic god" and use the paragon interrupt to stop him from fighting the Asari. If Thane is in the right team member slot (not sure which off the top of my head) he will wish the Volus "Sleep well, and dream of bulbous women."
