You were Paragon all the way through, weren't you? Therefore the new council will be multi-species but human led, which is definitely better than if you were Renegade aligned, where the council is all-human. I still save the council though, but it'll be interesting to see what happens without the original council members. Who will be replaced, how will they be different? I'm looking forward to it. Like Ayen said, you made your choice without the assistance of hindsight or knowing what will happen further down the line, so I say stick with your original decision and come what may.
