The spectral Harpists say ..'doing works of good' (?). ..and, for all we know, Meronia does think she's doing good.
(I was speaking for myself on both counts
) If you're the spawn of the Lord of murder and the chants talk about blood, death following in our wake, it's a logical conclusion to belive that it's our destiny to be or become that. (Not too dissimilar to what georgie did, the *rick.) Inneundo can be just as persuasive. ..especially if you're male and romance Jaheira - it's her #1 fear.
Interesting.. I'm not contesting that I do believe Bhaal to be evil, but I read somewhere you talking about Bhaal being the god of death, or some-such, and not murder; neutral, I remember that much for sure. Regardless, I did say, a few posts back, that I forgot about the symbol of Bhaal.
..and I'm still going to be stubborn about it.
