I think that Gygax's alignment system has some degree of trouble with these examples. With your vampire, for instance, I think that in the Gygaxian framework you have to say something like the disregard for the life, relative freedom and happiness of the women outweighs the commitment to beauty.
If the vampire, having turned the women into undead, lets them go rather than tries to dominate them, then in the Gygaxian framework I think there's even scope to argue that the vampire is not acting evilly.
Having a quick look through the alignment descriptions in the 5e Basic PDF, I notice that beauty isn't mentioned at all, and it's really quite unclear what "good" actually amounts to (for instance, we are told that the CG "act as their consicene directs" without being told anything about the content of that conscience - but presumably some contrast is intended with the CN who "follow their whims").
