I think Eastman was a pretty good character.
Here's the thing. Eastman and his philosophy were very clearly the product of...
1. Being alone in an area relatively free of the dead. He's clearly never had to deal with more than two or three walkers at a time, nor had to concern himself with other human beings (until Morgan came along, that is).
2. Having a roof over his head and plenty of food, water and other amenities.
What would Eastman have done if 10 people had showed up on his doorstep and he couldn't feed and house them all? What would he do if he encountered a herd? What if The Governor wanted his cabin?
I mean, the story of what happened to his wife and child, and then what he did to their killer, is messed up for our world. In TWD world? Where Andrea had to kill her sister, Carl had to kill his mom, Merle cut off his own hand and there was an entire community that was set up to lure in other people AND EAT THEM?
The whole episode, while well done, felt weirdly disconnected from everything else we've been watching.
