Probably. I meant more like "let's just round it up to evil". Either
that, or I wanted it to be one of those pithy Malcolm Gladwell style
aphorisms.

Anything that is commonly described as evil usually has a more or less
reasonable explanation behind it. Simply declaring it beyond 
understanding is, in my opinion, just not wanting to do your homework.

Granted, sometimes the homework is simply insurmountable. But it would
be, in my opinion, more honest to just say that.

If I had to just mark, say, the Dred Scott decision as simply
evil, I'd lose out on a lot of detail.

So it's a useful rule of thumb to me anyway.

You equate describing something as "evil" with "declaring it beyond
understanding"? I don't. I can understand evil (not always, especially
in extreme cases - but often). I've wanted to commit evil, and have
occasionally failed to resist the temptation to do so. I understand why
others would be tempted to do evil, and why they sometimes give in.
There are many people whose acts have been far more evil than any that
I've ever committed or even been tempted to commit, but I'm intelligent
enough to extrapolate from my own experiences, with due attention to the
dangers of extrapolation. To me, calling something "evil" does not mark
it as beyond understanding, but only as seriously undesirable behavior,
whether or not it is well understood.

Yes, and from the way the paragraph concluded, it's evident he stopped thinking
about it.

Please read books about Turing machines and automata to understand
the principles in assembly  and C first.

you're kidding I assume?

- how do Turing machine shelp understand assembler or C?
- how do Turing machines help understand got?
- what does this have to do with the usage of the word "evil"?

Why? Because "considered harmful" took too long to type.

Excellent!  Thanks!

I think you just showed how to write good code.

Use C++!

You appear to be using C++ already given your remarkably similar flame 
bait thread over on c.l.c++.
