Ahem, but I have to point out--and I haven't read the discussions on the forum here on the recent season finale so forgive me if I'm being redundant--that for a long time I've seen Glenn from the TV show to be very very similar to Luke. Both of them are generally great guys, and neither of them are willing to kill other people if they can really, really help it. And yeah Kennyftw, I think you're right--if Jane had died, and if it was very clear that it was Kenny's fault that she died (tho idk how that would work to keep in line with Kenny's character), or if something happened in addition to that to really rile up Luke's and Kenny's anger towards each other, I think that Luke would have put his foot down, though I don't think it'd be enough for him to want to kill Kenny or get into a true full-fledged fight-to-the-death with him.
