Forum:ME2: Geth Rewrite or Destruction

Something I never understood about ME2 is the fact that in Legion's loyalty 'A house divided' the Paragon choice is to rewrite the Geth, which basically amounts to indoctrination or brainwashing as you're forcing them to believe something else, while simply killing them is seen as Renegade. Personally I always thought it should've been the other way round as it makes more sense for the Paragon action to be removing them as a threat, rather than making the ethically questionable choice of changing their thoughts by force and having the risk of them going back to worshiping the Reapers.
