Prepare yourselves for a wild speculation, when completing the game you are loaded back to the time before the attack on chronos station, it's also Shepard's last dream, like I said prepare yourself for some wild speculation, what if Shepard did not wake from that dream, think about this for a moment because there is a possibly everybody might be happy with the outcome.
After making the choice on the citadel you run through the consequences of each, and yes, I'm saying all three have bad consequence, destroy kills geth and edi, control destroys Shepard mind, synthesis makes slaves, all three have crap consequences, but, and here's the wild speculation, as the consequences of the choices play out, Shepard wakes up startled in bed on board the Normandy just before the attack on chronos station, no one has won anything, but no one has lost anything either.
If we all get together as one group, we can agree that all three outcomes have consequences that are "generally" not acceptable, someone that likes synthesis will likely be appalled by the consequence of destroy, someone that likes destroy will likely be appalled at the idea of synthesis and consider control to be too risky, in the end the general consensus is that all outcomes have unacceptable consequences.
Sheesh, I rambled that somewhat, I hope you guys "get it".
