He just gets awful, doesn't he? The staggeringly creepy not-so-sub subtext of his drugging Gwen's drink in the middle of a bar in "Everything Changes" really pretty much sets the tone for him. Don't get me wrong, I can't be arsed to get outraged about such things in Torchwood (the people who freak out over Owen's alien sex spray make me roll my eyes so hard, like, it's TORCHWOOD, save the hysteria for a show that actually means something), but "How's your drink?" was so blatant, there's no way that wasn't intended. And his behavior just goes downhill from there.

My favorite thing is how the only time we've ever been invited to question his decisions, as opposed to the writers insisting that Jack is Right Dammit, is in "Small Worlds," when he gives Jasmine to the fairies (sigh) to keep them from attacking humanity as a whole. Which also happens to be one of the only times when Jack isn't operating out of self-interest, arrogance, or just plain thoughtlessness. Madness.

But as I said - it just wouldn't be as much fun if the show acknowledged that Jack is a bastard.
