She's, practically, the same person she always was...just with a Zerg instinctual nature that fuels her overwhelming desire of vengeance...she feels hurt and betrayed, beyond words. The novels were all confirmed cannon as a way to delve further into the lore where the game could not...and throughout that novel you come to discover that Kerrigan, despite her hybridization, still loves Jim as much as she ever did. She even offers him a chance, though subtly, to join her...
Even when he refuses, even when he sides against her with Tassadar and Zeratul, she plays with him like a sadistic lover. As she hunts for the Protoss, she completely bypasses Jim despite knowing he was there, when Tassadar, Zeratul, and Jim ambushed her...she leapt upon Jim first to deactivate his suit...then kiss his visor and show off for him by basically taking on Tassadar and Zeratul on her own.
I honestly do not believe that she would ever kill Jim, nor do I believe that he would kill her...despite their mutual claims of ending one another's lives. Both of them seem like the type that would stand there and try to force the other one into killing them to ensure that they, themselves, were not the one to do it... Kerrigan wants Jim, still...but she knows he'll never agree to become her consort.
I actually think that the end of the game was a plan on her part, that the Xel'Naga artifact did something far different than we expect, imbued her with Xel'Naga energies that will actually empower her rather than having deinfested her. She still has the Zerg hair-like tendrils...and they don't seem to be even remotely effected. All that we know of the artifacts is based upon Valerian Mengsk...who undoubtedly had his team of scientists testing the artifact fragments on Zerg and Terran subjects to study the effects. The Protoss themselves, including Zeratul and the Preservers, have difficulty understanding the nature of Xel'Naga ways, language, and technology...so why in the world would we assume that Valerian and his Terran team could decipher the Xel'Naga artifact's purpose?
They most likely found that it destroyed Zerg cells and left Terran in tact...coming to the logical conclusion that it would either kill or deinfest Kerrigan. However, what if the artifact's purpose was to actually empower a hybrid...which Kerrigan, technical, is. What if the regression in her state is only temporary and caused by the fact that the energies needed to prepare her for the final metamorphosis that would ascend her into "god-hood" akin to the Fallen One and the Xel'Naga themselves. She could have done this all on her own by getting the artifact before Jim did...but now she had Jim not only bring it to her...but use it on her, which may have been what she planned all along.
Now she's with Jim, the man she still loves...and quite possibly still the Queen of Blades, waiting for her ascention to take root...and in the perfect place to take Jim if she so chose. However, like I said before, I doubt she would ever force Jim to join her...but to play the part of the "good ol Kerrigan" as she transforms back...and then offer him the option of coming along with her at the promise of leaving the Terrans alone after Mengsk is destroyed... Well, the loss of love tends to weigh heavily on the heart, as we have seen with Jim...but to gain back what you have lost and then have it threatened again...that destroys people. He was a broken man...Kerrigan has him right where she wants him, with a false sense of hope...
All it'll take is a little push...and she can finally have the consort she wanted from the start...all she has to do is appeal to one bit of humanity and make him a promise that after it's all over...she'll leave the Terrans to themselves...and I think he'll jump.
