Not only that but after receiving a Nobel Peace Prize he proceeded to engage in drone warfare. Just in 2016 he dropped more then 20k bombs, in countries which we were not even at war with. Many in Africa. It was surprising how little flak he got for it. Indeed when he was elected in 2008 he got the best marketer of year award http://adage.com/article/moy-2008/obama-wins-ad-age-s-market... and he presented a great image.
> Which is worse: torture or killing?
It is kind of a false choice. But let's go with it, Obama effectively picked both. Anyone remember how he promised to close Guantanamo? Well it is still open. He picked both killing and continued torture. Yet people still idolize him and think he was so great. Again, that's the power of propaganda and marketing at work, AdAge's award was very much on point, better then Coke, Nike and Apple.
