Okay. That much is at least conceivable. I still wouldn't hand him too much credit, since I think his erroneous soulless assumption at the starting line kind of nullifies any good intentions of the act itself,
But though his assumption regarding what having a soul would mean was incorrect, the act of getting one was incredibly noble since the motivation was. Getting the soul was for love, sure, and not to save the world. But why doesn't he get credit for it? Or why is the goodness of it nullified? He did something incredible for the person he loves...as a vampire. That part is unchanged, even though his understanding of the scope of it changed upon receiving it.
If you accept the characterization of Season 9, I wonder if you'd also take into account the After the Fall comics, including this quote from Spike: "I earned my rest. I've proven myself. Not that I had to. I mean, I fought to get my soul back, what more do you want from me?" Even if you don't, I just want to point to it as evidence that I'm not the only one who interpreted Spike as being uninterested in keeping up the fight. It's pretty widely accepted among fans as a difference between Spike and Angel - ask what Spike's story is about and you'll get a range of answers, ask the same of Angel's and you'll generally hear "redemption".
Which comic is it from? I haven't read the Angel series from IDW; just the Spike spin-off, (which is considered canonical). In it, he goes to LA on a mission that Angel refused. In the "Devil you Know" spinoff which I haven't read fully, the synopsis describes him off fighting evil and going up against yet another plot to destroy the world. So, it says two things to me:
1) He's still clearly fighting for good, whether himself calls it active redemption seeking is another thing. He says things like the above quotation because often he resists ideas with words when backed into a corner( especially when Angel is involved); when the notion occurs to
him that it's time to do something, he acts upon it. Not knowing, (or not remembering) the context of that quote, that's all I can provide, but:
2)This is the problem with handing characters off to other various teams of writers, whose individual stories probably aren't all checked by Joss, (though the arcs are). I think it was hard enough for the group of writers on the show, handing characters off between episodes, to maintain consistent characterization, so I don't expect it to be clean, here. All I know is that Spike isn't
actually resting on his laurels, (although apparently in this instance he
says he is), and he's fulfilling missions Angel won't take on. Keeping up the fight. Certainly in the Btvs comics his priorities have shifted back onto Buffy and helping her mission specifically. Which is classic Spike, but doesn't mean he's "done" saving people any more than she is.
In terms of Spike seeking redemption from the eyes of fans, my answer is that he doesn't need to but is anyway. Most important of all to him is to be redeemed to the specific people he's hurt. And when he fights, no one is forcing him. He doesn't care about titles and maybe isn't sure yet what it all means, but he knows he wants to be a part of it, and he is. Show me Spike moving away to some remote location (with or without B) where there are no demons and no missions, and I'll concede that he indeed thinks he's done!
