no point to the traps

The entire cube is a 26x26x26 maze. I thought that this was fascinating enough. If the structure was built to test people why kill them almost immediately? In this movie's maze scenario ( characters ) they have chosen people, when teamed up, ( and assuming they actually find each other) could work together to get out. If they were purposely chosen for their skill sets, why have traps too? seems counter productive and a waste of planning / effort.

ie. " ok, we've spent months searching for candidates who could effectively decode and navigate our super maze. we've kidnapped them. we've put them in the maze and yes, holy smokes, out of 17,500 cubes they've all found each other. We can finally see the ingenuity of of a select combination of minds against the odds of our trillion dollar fun *beep* they all got their faces melted off. oh well.
