In considering
the reported timeline of how BK's TA firing came about:
Sept 23 - "altercation" with professor
Oct 3 - meeting with professor to discuss "professional behavior"
Oct 21 - professor emails BK that he has failed expectations discussed at Oct 3 meeting
Nov 12 - meeting to discuss an improvement plan
Dec 7 - meeting to discuss how improvement plan is going
Dec 9 - second "altercation" with professor
Dec 19 - terminated
It's interesting to look at the timeline, knowing the murders took place the night of (
technically the morning after) the Nov 12 meeting where an improvement plan was introduced. It's also interesting to think about what's been reported about how BK completely changed the way he graded papers right after the murders. Until we learned of the firing timeline it was somewhat implied via media that the change in BK's grading style was related to the crime (perhaps even that murdering relieved his anger, at least temporarily?). But it appears the change in grading style is almost certainly more to do with the improvement plan than anything crime related.
But still, I'm left to ponder that Nov 12 meeting, literally right before the murders. My pure speculation, but was BK reaping some type of psychological benefit or "high" from the harsh grading, an abuse he learned on Nov 12 that he would no longer be able to indulge in? How would he get his fix now? Were the female student complaints and subsequent improvement plan that they triggered further evidence that BK didn't have ultimate control over what females thought of him? Was there a way to indulge in an abuse that could never be overturned? Does any of this start to unblur the image of motive?
All just MOO.
