but why is just living such a big thing? if you feel horrible about yourself and life in general because you had to slaughter 5 of your closest friends just to stay alive, what's the point in living? wouldn't dying be better than living with that? moral apocalypses might be annoying to see, but they are an interesting look into the human psyche. you act like going around killing people you've known for months/years is easy. empathy,regret, guilt, etc is hard coded into people, it's not an easy thing to ignore.
don't get me wrong, people definitely need to change after a zombie apocalypse. but it's all about moderation. you can't act like nothings ever happened, but you can't just go full on survivor dick mode.
I'm glad there was someone like dale and shane around. they created moral problems. dale was absolutely correct when he was talking about how they were going to murder that guy just because of something he might do in the future. and shane was right to be so hostile towards him because of that thing he might do. they were both right, which is what makes things interesting. two choices that are completely opposed, but are both correct in their own ways.
they just killed off two of the extremes of the group. I wonder if others will fill the void (possibilities right now are sort of glen for dale and andrea for shane), or will they just leave it and have a bunch of moderates.
