Astrid conspired with the archon to have Sharon bound to him, or at least went along with it, among other things. The only views on Astrid we have, thus far, are from our brief interactions, where she immediately sold us out to get advantage on Sharon because her only desire was taking what she had (even though it involved also binding Sharon to the Archon,) Sharon (and Andrew) being rather vehement about it, and our bitch of an MMA instructor who thinks she's just grand.
Like, I can get the perspective; she owes the MC nothing (well, beyond the fact we DID stop her from probably breaking masquerade) and is seeking to just advance herself however she wants, but likewise we owe her nothing. If one approaches it as someone embracing vampirism and the like, once can appreciate Astrid but still recognize she's, at best, a dangerous wildcard. If you embrace the humanity path and view, Astrid is up there with the archon on exactly the sort of vampire not to be; callous, jealous, petty, and cruel.
Per super mind whammy? I dunno, probably get certain folks to forget the MC and Laurie existed or the like.
