All progress is built on the "gutting" of that which preceeds it. It's in the definition. This is where it gets muddy, because something completely foreign to both the Lifestream and Shinra, both as hiveminds, comes in: morality.
Aerith specifically, who is often represented as a poster child for the former, actually spends most of the game as a True Neutral. Seeing things for what they are, calling out bad (and good) shit regardless of who or what was responsible. This is highlighted when she speaks about how beautiful Midgar is and how amazing it is that people could come together and create something so ingenious, all in spite of its flaws and the methods to get there. The poor judgment and the corrupted mentality of a man like President Shinra, the apathy and voluntary ignorance of the body that makes up Shinra as a company. It still produced something that somebody like Aerith finds beautiful.
Conversely, the Lifestream produces monsters, weapons of mass destruction, causes cancer, has self-destructive tendencies, and has itself directly threatened all settlements and life.
Both are not intrinsically good or bad. They are different physiologically, but they both produce amazing feats while walking very similar paths.
