I think a few good tvtropes for an aspiring villain to read are:NarmDarkness-Induced Audience ApathyWangst
A lot of the reason I've never really taken the fiction written by Tony G too seriously is that practically everything he's written, and especially regarding the Amarr and Caldari, suffers from the above. There's one thing to have "bad guys" and then there's making things so contrived, so melodramatic, so histrionic, and so overplayed that you end up being unable to take them seriously because they've managed to reach the point of just being so stereotypical and poorly executed they enter the realm of absurdity.
But I guess that's fine, I mean that's basically the definition of say, 1960's era comic book villains. However, I think society has moved on in some respects from accepting the concept of villains being evil just because they're evil which can be seen in the development of series like the Watchmen, or X-Men which explored more nuanced concepts about society, people, and good or evil.
I suppose it depends what you prefer out of Eve in playing a villain. And to take the comic book analogy further as example, whether you prefer the villains from Batman and Robin
or if you prefer the villains from the Dark Knight
Because there's a difference to me in execution with those examples, and personally I think I prefer the Dark Knight so I just tend to shrug and move on with people who base their characters on the work of Tony G because it usually comes off as trying too hard, poorly executed, and sometimes unlike Batman and Robin which was intentionally meant to be cheesy, those characters actually seem to come off to me as unintentionally cheesy. Which almost makes it amusing, really.
