What do you base his on? Is it solely on behavior after the chip? If so we aren’t really playing on equal footing are we?What I meant was that soulless Spike is better than soulless Angel
Angelus and Spike both killed, raped, and tortured (we saw Spike complicit in torture at least twice on the show WML/In the Dark). Spike tried to kill Buffy a number of times, Angelus killed her teacher. We know Spike slaughtered an orphanage and Angelus killed kids too. Angelus wanted to suck the world into hell, Spike wanted to continue to eat/kill people on this plane of existence (happy meals with legs) while watching Manchester United. So not sure how you can make the argument that Angelus was 100x worse than Spike. Angelus was more artful with his evil, but Spike enjoyed the crunch and got off on his kills including Slayers so he was no Boy Scout. Not even compared to Angelus. And he did that all on his own for a hundred years.
Bottom line is we don’t know how Angelus would have reacted with a chip. I have my theories but ultimately the story never went there and we can’t compare apples to oranges and call it a day.
