seems like a plot hole in the purpose of the mission / ending

Spoiler alert, obviously.

So Beka knew she was actually just delivering spy info to the cylons, rather than a virus. With a virus, ok I guess it makes sense that you need to get into their base and upload it to a lot of their systems at once. If you have information they actually want, surely you can just find a much easier way to give it to them.

I don't get why she'd want to put herself in such personal danger. Deathwish or something out of grief for her husband? Couldn't she have just gotten her tactical information to the cylons some other way, and let someone else go out with the results of the virus project she was working on? (She could have made the virus not actually work, perhaps). Maybe it did seem to her that going herself to upload this data was the best course of action.

She doesn't know that military were on to her, so her own actions maybe make some sense. But the military just needed the cylons to believe that there was a traitor giving them information. Seems like there would be ways to do that that wouldn't put a whole ship on what turned into a suicide mission.

Only way I've thought of so far for it to make sense is if the data upload from the comm station somehow goes directly into the sum of cylon knowledge, without them being aware of the source and thus without reason to distrust it. Otherwise just fake-hyjacking a raptor or something and beaming a signal towards some cylons should do the trick just as well. Unless delivering the data through the comm station somehow stops the cylons from believing it came from a Colonial "traitor", there should be far less costly ways to deliver it. And nobody in the show said anything about it working that way.

So it looks to me like the Colonial military just sacrificed a lot of people and assets needlessly in the process of leaking some information.

For me, that ending really undercut the drama of the action leading up to it.
