Possible, but not sensible. People who are flipping out at the callousness of the other climbers have to understand what it means to climb to altitudes above 26,000 feet. As many have pointed out, simply surviving and getting yourself up/down at those altitudes is a tremendous feat.
Could the other climbers have tried to bring him down instead of pushing on to the summit? Sure. But the simple fact is that if you choose to climb to those altitudes, you also choose to accept the consequences, and you don't expect anyone else to help you if you can't make it.
Everyone who goes up there knows what's at stake. There are lots of dead bodies that will be up there for a very long time, and lots of climbers who reached the summit or returned from the summit by stepping over or around dead and/or dying climbers. Its just the way it is.
Wow, what a bunch of morons...
