Esther is Wednesday AddamsEsther was previously adopted by the Addams family (using a different false name and disguising her accent, naturally), but was unable to carry out her usual seduction-and-killing plan because the Addams family took her sociopathic behaviour in stride.
Esther was punishing Kate specifically.Although Esther was trying to seduce John, there are moments in the film where it comes off as though Esther is enacting her own twisted version of justice on Kate- she confronts Kate with how Max nearly died because of her drinking and tells Kate she's taken her family for granted.

Her affection for Max dwindled when Max proved more loyal to Kate than her, which is why she turned on Max after John rejected her.
