Hum, I don't really see that unethical behavior by the part of the SGA crew, but rather being in a different place than SG1.
Because from what we've seen there's no possibility to co-exist with the Wraith. Their foot soldiers can't be convinced to join the good fight. There's no Teal'c to remind the humans that the other side isn't uber evil, instead there's a genetic experiment descendant and a hunt for sport survivor, both with reasons to hate the Wraith more than the Earth born crew.
The retro virus was their honest attempt at trying to beat the Wraith without killing them. The smart thing to do once they saw how the retro virus works, would be to dump the soon-to-be Wraith in a backwater, barely able to sustain life planet. Or pretty much execute them all while they were unable to defend themselves. Instead, they again attempted to keep them alive.
This isn't to say that they're the white, crispy clean, hats. No. They're not. And some of the decisions are stupid beyond belief, understandable only within the context of needing a big finale for the season.
But while it might be unethical to do some of the things they've done, the only alternative was to kill what were at the time human beings. Discussing ethics with regards to the Wraith is like discussing ethics with regards to vampires in BtVS.
Is it ethical to kill a newly risen? No, but it's efficient.
Is it ethical to turn Wraiths into amnesiac, can't defend themselves temporary humans? No, but it's efficient.
