Rushdie’s own narration ascribes the freed imagination to Sufiya without character support

Evidence

Yet there is something profoundly unsettling about this idea of a ‘freedom’ which resides in rising ‘above everything’ (earlier in the book, we have already encountered the idea of ‘floating upwards’), hence being able to commit limitless, senseless violence. And if this is indeed what Sufiya Zinobia has become, then it is very difficult, because of this moral perplexity, for a reader to sympathize with her in that last episode where she finally manages to kill Omar Khayyam Shakil himself. By then, it is no longer a confrontation between shamelessness and shame bur, rather, between a man who is of course clearly a moral cripple, and a woman who has become - not in the metaphorical but in the most literal sensea beast. — Aijaz Ahmad, In Theory, 592
