She only helped Lewstrom remember the truth about himself as a last resort, when violence didn't work. :-\ If she'd been able to kill him with a sword, she would have continued to sit on the secret that could have saved him centuries of empty sorrow.
I agree with Aebliss. She is not saving the world because she respects and cherishes lives, she just doesn't want to get annihilated. She is a very clever drow who knows how much she is worth and on top of her other flaws has become arrogant because of it. I can only hope that she doesn't find a way to hurt Glon after that.
That's true, but you can't say that she is making the world worse only by existing.
The majority of YAFGC heroes are evil
monsters, and they are routinely doing bad things. Yet no other character has earned as many hate posts as Arachne. Why? The only reason I can think of is that she's better than the others at being bad. Why don't you hate Bob? He's an evil monster too!
(As for me, I neither hate nor love Arachne, but I find her very entertaining to watch.)
Despite the fact that the Black mountain inhabitants are evil, they sometimes do good things, even if for evil reasons. Goethe wrote thus about this subject:
Faust. ...Well now, who are you then?
Mephistopheles. Part of that Power which would
The Evil ever do, and ever does the Good.
