I've always been convinced that email was written only to be an affidavit, so that they could defame Vic as outrageously as possible behind the protection of the law. It wasn't defamation when she said it originally because it was in private directed at him, and it's not defamation when it's included as an affidavit, but because she wrote it 'spontaneously' in the form of an email it has the power of defamation behind it. If I recall, the email has all three forms of per se defamation in it, and not only did it come off as more 'sincere' by being written as an angry 'private' email, it would be harder to work in all those details in a traditional affidavit and explain why it should be included. Plus, she'd be perjuring herself, where in this case all she's saying is that she sent the email and he didn't deny it (both of which are true). It made her look more sympathetic than if she'd written an affidavit, too, as it made most people say "Oh, she's a hurt woman being spiteful" and not "she's a snake turning on her ex because it suits her to do so" as an affidavit would have.
I think the email served three purposes:
1- to hopefully turn people like
@Svetlana against him (because they're psychopaths who don't want him to have any support or human contact at all and do their best to push everyone away from him by force or by shame) while maintaining Specht's 'innocence' and sympathy by playing the 'hurt partner' angle, which falls entirely in line with how Monica was doing things at the time.
2- to harm Vic, because they absolutely 100% were trying to get him to JewWario himself in the beginning. There's no convincing argument whatsoever where the early stages of kickvic weren't engineered to get him to off himself so that no one would dig deeper and everyone involved would come out of it looking like tragic heroes. Many people involved in the early stages were Channel Awesome members, so it's absolutely impossible 'he kills himself from guilt over things he's done that haven't come out' wasn't a possibility they considered, even without the things that have come out later that make it clear people like Monica knew exactly what psychological buttons they were pushing. We know they were desperately hoping something would come out proving them right, and so there's no way they didn't consider 'he'll kneejerk react because he's afraid of being caught doing (thing we don't know about)'.
3- to massively defame Vic via the lawsuit, because by the time it was sent they already knew they were getting sued, and their strategy from the very beginning has been "vindictively damage Vic as much as possible to punish him for fighting back and hopefully scare him into backing off by promising to drag him through the mud constantly as long as he keeps pushing" - as lawtwitter constantly repeats for everyone, just in case you missed it. I think this was the primary reason for doing it, while the other two were gravy. By the time it was written, 1 and 2 were less likely to pan out, but Specht and the others would absolutely know by then that Vic would apologize for her hurt feelings over bothering to deny the accusations since they were in private. Thus, she could outrageously defame him, wait for him to apologize like a normal human being instead of bothering to argue about whether he did it all, and then submit both of those as an affidavit saying "Look at how he didn't deny
any of what I said! I was just an angry and hurt ex-girlfriend who can't be blamed for what I said to him, and yet not even the worst things I said did he deny!"
