to show us failure of another kind and the consequences of it, especially for a Forsaken. The other dead Forsaken all met their ends from direct confrontation with either Rand and/or his allies. Even Moghedien, coward that she is, was personally involved in her plots, except her flighty nature kept her alive.

Graendal however was extremely lazy (makes sense for her indolent nature) and used Compelled slaves to do most of her bidding. If she got off her plump ass and waded into battler herself, she could have maybe won [against Perrin]. Graendal's mistake was not keeping a closer tab on what was happeneding, something she could have avoided if she was present in the "where" that the "what" was happening.
