One of the ultimate Grey and Gray Morality moments in Mass Effect 2 was when you are given the choice to either kill all of the Heretic Geth or rewrite them. Mass genocide vs mass brainwashing, neither of them are very pleasant options, but you've gotta make a choice. I personally went with rewriting them, but it kinda feels like everyone did that. I want to double check though, what did you do?
Also can we not bring up how it had little effect going into ME3? Let's focus on what you did on ME2 and what you would do in a situation like this.
