I think real problem with the Dark Forest hypothesis is that it assumes alien civilizations at a very high level of technical development would somehow have not also made any sort of moral or ethical progress. Even humans, in a few thousand years have gone from winner-take-all, kill 'em all, to universal human rights, rules of war, etc. (sure, we aren't doing a perfect job, but we clearly have made some progress - by the time we're sending ships to other stars, I'd like to think we'll be farther along yet).
