If somebody is given a task which is impossible to accomplish, then who
is to blame? The one who failed or the one who gave him the task?
The controller was not given a task that was impossible to accomplish.

Very few tasks are absolutely impossible to accomplish. Whether something is
possible for a particular person with particular skills to accomplish in a
particular situation is another thing entirely. The aviation industry goes
to great pains to take note of the human factors involved in what goes on,
and this entire incident is (very sadly) an excellent example of how a
combination of (often unrelated) human factors issues can combine to cause
loss of life.
