First time checking this thread again... so far, I'm liking Tyreese, so maybe this show can rebuild itself without Shane. I absolutely do not deny Shane made mistakes. Really, it's like Pearl Harbor in a sense. I can't remember their names, yet the one friend thought the other friend died overseas, so he's the one to deliver the bad news to his friend's girlfriend. Could They have waited a little longer? perhaps, yet I understand (despite the fact I'm still a virgin,) sometimes people get intimate to cope with stress. I don't fault Lori or Shane for that. And come on, the wiki, the actors and the producers have all practically said it..... SHANE THOUGHT RICK WAS DEAD. We saw the episode very clearly. There was no denying Shane didn't know he was alive. Yeah, he pointed the gun at Rick while Dale watched, yet the guy came to his senses again. Lori kept giving Shane mixed signals.
Lori: "YOU STAY AWAY FROM ME AND MY FAMILY!"
Shane: "I made my mistakes, so I think I should just leave the group."
Lori: "YOU'RE LEAVING? THE NERVE OF YOU!"
(after Shane shoots another man so Carl can live)
Lori: "please stay Shane."
Shane: "do you really mean it?"
Lori: "yes."
(a few episodes later, Rick and Shane have their disagreements, yet Lori again spits on Shane for no apparent reason)
Lori: "even if you're the father, you will have no part of it's life!"
At this point, Lori starts being pushy, having Glenn and Maggie do her errands, risking their lives for abortion pills she decides to puke up, and makes an enemy of Andrea, not to mention she can't keep up with her own damn son enough as it is. "WHERE'S CARL?!" Off stealing Daryl's gun no less than twice, and going off into the woods to mess with a zombie with NO PARENTAL SUPERVISION! It's a wonder he didn't end up like Sophia, the way she watches him, With Rick not being that much better. For some reason, Carl was comfortable coming clean to Shane about it and not with Rick first. Well anyway, Lori goes to get Rick from town, and instead of asking Dale or Tdog to accompany her, she drives herself and crashes while trying to avoid someone in the road who was already dead. Shane goes out to get her because she doesn't need to be out there anyway and goes to get her for her own safety, and..... she gets angry at him and asks Rick to kill him. Well, the episode 18 miles out, Rick and Shane have their fight, and They get all that energy out of their systems and relieve the stress They have with each other. After all is said and done, Rick tells Shane to forget Lori. She's HIS wife, and he needs to accept that, which he finally does. Rick tells Lori he made sure it won't be a problem anymore. By this point, Shane and Rick are still a little tense with each other, yet They most likely would have gotten over it with time. Yet Lori has to talk to Shane. COME ON LORI, Shane is very unstable at this point. Stay silent and leave it alone. Nope. She just has to go talk to him. "Yes Shane, I really did have feelings for you." You know the rest.
As for the final confrontation with Rick, did he intend to kill Rick? I'm going to have to say, probably. Yet when it came time to pull the trigger, could he do it?

Q: The sense I got during that final scene was that Shane is processing like 10 million different things at once and trying to make sense of it all. He’s thinking about his relationship with Rick, his relationship with Lori and Carl, the safety of the group. In terms of Shane’s mental state at that point, what were you trying to get across?
A: There’s a whole part of the character that I think some people may or may not pick up on, but I think there’s a part of Shane himself that knows he is no longer fit to be among the people. He knows how much of a danger he is. He knows now he’s killed yet another human being, and I think a part of this is him really spurring and challenging and getting Rick to step up and encompass what Shane has and take Shane out. I think there’s a suicidal flavor. There’s a flavor there that’s really saying, “Come on, man, I’m challenging you to be the man that’s fit to raise the woman I love and the child I love and my child on the way. Come on and step up, raise your gun.” And there’s a part of him that so desperately wants Rick to be that man, and when Rick finally does it, there’s an element of some sort of relief.

I think at this point, whatever was going through his head at the end is just up to our own imagination.
