I mean, I do agree intuitively that I think they are different, but their circles have begun to intersect to some degree even if they might never superimpose. Rick is not the same idealist Rick we saw through some of Season 2, I think things started to really change for him when that barn door was opened in mid-season.
Both men do act in utilitarian fashion and have the tribal loyalty, but along with when you have said here:
I would also say thatMy opinion is that with Rick we are seeing what happens to a person with a decently functioning moral compass when he's subjected to extreme terror and grief over an extended period of time. With the Governor we're seeing what happens to someone who is only a good citizen because of legal/civil boundaries, not moral ones, when those legal/civil boundaries fall away (worse if he then gets a chance to set the next set of legal/civil boundaries himself).
I expect in the mid-season finale to see Andrea having to make a choice, which will end up further defining her character for good or bad.
I think she hasn't seen that the Governor is a 'slimeball' because he has aspects that she naturally resonates with. It's easy to see someone is a slimeball when their aspects don't mesh as naturally with yours. That's why I think, if she finds out what happened to Glenn, then her character is on the line -- at that point, she'll show her own character without any confusion. (AKA, is she loyal to her friends and willing to give up her own wants to help them, or will she sell out for what she personally wants, with someone who is morally dubious at best?)
