Haven't played the game since I was too worried about the direction bioware was going but have read up on the options and everything. Glad I didn't buy the game. However the only option I could give is destroy. This is due to me destorying the renegade geth since I thought they should die for their beliefs instead of them being overwritten into a new set. therefore no way would I allow control to a bunch of truly homicidal machines like the reapers. Synthesis, yeah I can just see the reapers indoctrinating people over a longer period of time and beginning the cycle anew so I must destroy them. I understand its a horrible option but I think its the best so that all races can truly be free of this cycle even if I am sentencing a lot of them to death and wiping out genuinely friendly synthetics who do deserve a chance at life.
