John Gacy, one ofthose serial killers whose efferate homicides incided his name and memnory in the collective USE imaginary, was an active member of his community, he was liked by his neighbours.
And he is one of the examples of the fact that human nature is complex, one of the reasons the alignment system started to get old, in these days we have a more mature (or disilluded, or cynical, pick your preference) society, the old good clear and neat distictions doesn't appeal so much, was John Gacy acting when he involved in the life of his community in a way that made him likeable? Or did he really believed in what he was doing despite being a serial killer?
Maybe Shadowheart is acting, maybe she do believe in Shar and doesn't find so much of a contradiction in that moment of simpathy she felt for the thieflings.
Or, maybe, being pragmatic she understands that to show simpathy is the best course of action.
