Wrath and Lust don't quite mix well together so yeah, they're going to hate each other.
It depends on the category of Allocer's rage. For example, Abaddon's rage has been imbued with magical properties by the Infernal Spring. That would basically make him the Atrocitus of Hell. Abaddon basically has the same temper as Kratos, only he doesn't stop to have sex with women, on levels where there are women. Most forms of magic that would essentially calm him down won't and don't work, not even Lilith's seduction, pheromone-laced webs, and powers to make him see what he truly desires. If Allocer's rage is simply a pissed off response to his crappy life, then he could be calmed down normally (like, let's say give him one or two balls of yarn) - which would make him vulnerable to her charms.
It also depends on the way Kitana seduces. The CS stated that she had both skills in Seduction and Lust Pheromones, but now that I think about it, there are many ways of people to seduce. The Incubi seduce by this sort of Mystique-like shapeshifting, where they turn into different races but not get their powers - this is a physical power, like some sort of mutant ability. Succubi, on the other hand, do it via illusions and hallucinations, as well as hypnotic words and sensual dances, which is magical in nature.
I assume Kitana's way of seducing is by magic. So, if Allocer's rage is not magical in nature, and Kitana's way of seduction is, then Allocer has the disadvantage as she can make him see a hot lioness in his mind. If Allocer's rage and Kitana's seduction is magical in nature, it comes down to strength and experience. Resistance is strong, or it can even be cancelled out. If Allocer's rage is magical, and Kitana's seduction isn't, then Allocer is free to gore Kitana as she attempts to seduce you in vain. And, if your characters are both angry and seductive without having a magical kick to it, then you guys will kill each other because Allocer would be all "WTF is this disgusting female doing? She has no fur, ew." and Kitana would be all "this is like, sooooo gross get away from me kitty," It's basically math.
