Medical ethics violations

[murasakisilver.livejournal.com]

I'm looking for stories where either Beckett or Keller blatantly disregards medical ethics (for instance, by administering a treatment without properly testing it first) and there are serious consequences down the line. If it's Beckett, the consequences need not show up while he's still alive.

The longer and darker the better. McShep preferred, but I'll read anything!

Stories where the ATA gene therapy causes problems are absolutely welcome, but I've already read everything recommended in this post.

Thanks!
