Carmilla - did she intend to turn Laura into a vampire?

Just finished the book, and I like how ambiguous Carmilla’s feelings towards Laura are (i.e. whether her love was real or just a tactic).

I’m inclined to think that there was something more to it, seeing as most of her other victims were killed far quicker than Laura (within only a few days). Even Katherine was dead within only 3 weeks, where Carmilla planned to stay with Laura for 3 months (according to her “mother”).

Carmilla also keeps saying that Laura should love or hate her in death and beyond, and that she will become a butterfly. This leads me to believe that she is planning some kind of transformation for Laura after her death, I.e. becoming a revenant.

I think she must have had some particular fondness for Laura over all her other victims.
