Why do you mention that he was "very capable"?
How is that relevant to the situation? You are actually saying that his death is more regrettable because he was a very capable teacher. So, if he'd been a tramp, that would make his death less regrettable?
Anyway, how do you know how capable he was, as a teacher? You can deduce that his capability as a cyclist must have been somewhat below par, but that is all.
My first instinct here was to dump a few insults on you, but I'll treat you with some respect.
As to your second point, I don't know the person who was killed. However, I recall the television report that I saw interviewed someone from his school, who spoke well of him and his teaching ability. I assumed that person was reasonably honest, so it was fair to infer that the late bicyclist was a good teacher.
As to your first point, I may have worded my statement poorly. I apologize if it caused you anger or anguish. What I meant was that it was sad that he died in this way. Further, I felt that it was likely, since he was a capable teacher, that the students in his class would suffer pain from his loss, and I was sad about that.
I didn't realize that my statement would cause someone to jump all over it.
