Hee, sorry. Entirely my fault; I was not nearly as careful or explicit in my comparison as such a comparison requires. It wasn't actually my intent to attack Diana for her action. Her conversion to Kane unsettles me the same way, say, Dinah killing Savant would have unsettled me, even though Helena's (morally equivalent) killing of Mandragora earned an emphatic "hell yeah" - it's a betrayal of self, and as someone who loves the character, that's like watching a super-devout Jewish friend chowing down on cheeseburgers. It's not "I have a problem with you eating cheeseburgers," it's "you're doing something that should shake you to your very core and will certainly perturb your loved ones, nothing good can come of this."
Thing is, though, Diana's whole mess with Kane, being totally fantasy-based and built around a fairly alien worldview, does not necessarily come across as being particularly problematic or a big deal - there's no automatic common language or understanding of what this should mean to her the way there is of what kosher means to a devout Jew. However, her situation does map perfectly to the concepts of sex and fidelity and prostitution in our own wider culture - which do get across how problematic and what a big deal Diana's behavior is in her context, since everybody understands them completely. If I say, "Diana pledged herself to a strange god to save her mother," nobody is going to see why that makes me worry for her or why serving Pele should be a step up in terms of her... internal moral fidelity I guess. If I say "telling an amazon that would be like telling a random American that she ditched her husband and slept with a rich guy so he'd pay for her mom's surgery," though, that's a bit clearer.
Also makes it more obvious that I'm appealing to a common language pool for comprehension's sake rather than endorsing stupid, dangerous sexist bullshit to impugn a character ("whoring" as an actual intentional insult seems to me about as connected to reality as, I dunno, "thetan" as a legitimate explanation for a headache, which obviously makes it totally toothless there since you're all mindreaders amirite?). I should probably not have skipped that whole "establish the metaphor before using it" step. -.-
