There's two reasons for firing somebody in my experience. Hiring a bad employee and hiring the wrong employee.
This list is mostly about the first kind I think - because of the line "Some people who get fired react by fixing their weaknesses". The wrong person doesn't have "weaknesses" to fix. You hired a round peg, when you should have hired a square one. Its your fault - not theirs.
(Okay - the "bad" employee hire is your fault too, but it's a different kind of mistake.)
