^ while I agree with most of your points, Spike did not always feel redeemed. Remember that one mad slayer who locked him up and chopped off his hand (or hands, I can't remember). He was later asked why he wouldn't fight back, say something; and he said something like he wasn't the one that killed her parents, but he's still responsible for countless others. He did not feel redeemed than. He had countless sins to atone for.

Although nothing would change and Spike would have an awesome ending if he hadn't crossed over to Angel, if what Angel is all about is redemption, I find he fits quite right.

Maybe that wasn't the reason he was crossed over to Angel, because I always thought it was for comic relief or his fandom; but I don't think he lacked purpose there. If anything, he was a rival for Angel for the Shan-shu prophecy, where the vampire with a soul would eventually be made human. And at the end of the season, Angel lost that. That prophecy, the ultimate goal, became Spike's purpose.
