Why were Olaf's Parents murdered?

[counto]

We all know Count Olaf is the main antagonist throughout A Series of Unfortunate Events, with exception of Esme Squalor and the Sinister Duo. 

But is he really all that evil in the book series? 

Olaf was a volunteer and later turned to the fire starting side before the Bad Beginning. 

The main reason is vaguely explained in the Penultimate Peril, that Olaf's parents (who were also volunteers) were killed by poisonous darts at the opera (La Forza del Destino) making him an orphan. It's implied that Lemony Snicket, Beatrice and Bertrand Baudelaire were partly responsible for their deaths. 

The question is: Why? 

And if not, what would've happened if Olaf's parents weren't murdered? Would he still be evil?

There isn't sufficient data to determine the truth. I have always presumed that Olaf's parents were particularly dangerous and inflammatory agents in the world, whether as part of the fire-starting side of V.F.D. or just on their own account; but I feel that the Netflix adaptation's innovation of the whole business being a terrible accident was actually very effective, and presents everyone in a better light than the version of events in the books, which sounds like (but is not necessarily) a targeted assassination.

Hmmm. I’ve always hated how they did it in the series, though I’m wondering how much of that was the timeline change and the clumsy introduction of the sugar bowl. The accident plot line would’ve worked well on its own.
My own interpretation(which is really just fanfic) is that it was an attempt to assassinate Olaf that ended up killing his parents accidentally.

The moment when the building committee meeting took place within the chronology always fascinated me. I have my own theory, but no matter what, I think clearly it was a building committee meeting, and not an open meeting for any VFD member.

The fact that there was a call list indicates that the meeting was for specific people, don't you think? And the minutes of the meeting were not supposed to be read by people who weren't at the meeting. Also, when L could not attend, his representative D would appear in his place. All of this evidences that the committee meeting was a meeting restricted to a few VFD members.

In addition, this was a committee meeting, which by definition is people delegated to discuss an issue and make decisions on behalf of a larger group.
