Green robs the choice from everyone in the galaxy
Red robs the choice from EDI and the Geth in laying down their lives for organics.
Both are technically equal in that respect. The only thing left to consider then is which cause the less damage to life. If red takes away synthetic life, an equally valid form of life and green doesn't, why would you choose red?
Green may have future consequences of disaster from problems with future generations but that's besides the point. The current point is to stop the cycle of harvesting and destruction of life and to prevent the thing that robs the people their own freedoms, even if that's to destroy themselves.
Because, as I stated about 2 pages ago: Destroy kills soldiers who were fighting to defeat the Reapers. The Reapers, in all their horror, set the stakes at "everyone dies or we do". The only choice was to fight and possibly die, or simply die. The geth consensus agreed to fight the Reapers. They agreed to stop being the tools of the Old Machines and join a fight where the ONLY outcomes were death or victory.
Soldiers are sacrificed in war. It is tragic, but every soldier knows the burden, and due to their unique nature, the geth were all soldiering in the war. As a hive mind, they have no "civilians" in the traditional sense, and if the choice had been, "Earth gets vaporized, killing all human life, but the Reapers die", Shepard should have still pulled that trigger. He/She was willing to burn the Batarian system in Arrival to stop them, and that was accepted as a necessary move, even by the Batarian survivors (if you have enough reputation). This war is a whole 'nother level of butchery, and the stakes have escalated to include genocide under the scope of "sacrifice few to save many".
It's not good, but it's not the betrayal of your allies that Synthesis is. They sent you to kill the Reapers, no matter the cost, not open up Pandora's Box and turn everyone into some sort of Reaper-creature in keeping with the Catalyst's vision.
And again, this is "Worst Case Scenario", if the Catalyst (an immensely flawed being) is completely right and truthful in all its cryptic statements, and we have very little reason to trust it at all.
