People who:
(1) Behave "friendly" to students whom they first meet {WARNING: THEY ARE FAKE
NICE PEOPLE}.
(2) Start giving hard as heck
homework to them
(3) Subtly kill students by homework, then
(4) Directly kill students by homework
(5) Announce the exam dates with glee
(6) Give them stress by including notes which aren't even in
the goddamn syllabi and sends them to hell
(7) Do nothing but giving homework, dont even know how to teach
They do this much of these, but NEVER get karma.
