Hmmm. So, evidently, they were not (successfully) taught thoughtfulness...
Now I don't subscribe to the theory that the teacher is automatically at fault when the student doesn't learn, but I don't subscribe to the counter-theory that the student who doesn't learn is entirely at fault, either. Whether teacher or student bears the responsibility (or the two must share it) must be assessed [or is that ):-> "examined"?] on a case by case basis. Indeed, under some circumstances, environment bears the blame--as has been pointed out.
