Rick states, "I don't take chances anymore," and I would argue that such a stance is an example of wisdom on his part, learned the hard way out on the road trying to survive. Better than most, the group followed by the story knows that usually other people are the real monsters. We see that those who do join the community (Morgan) are kept in custody for a while similar to house arrest to make sure they aren't dangerous, asked questions about their time out on the road, etc. This serves the purpose of allowing the people in charge of the community to get to know the newcomer and attempt to ascertain whether or not they are a potential asset or a danger. Again, a very good idea, in my opinion.
Viewers are then faced with the idea that when violence is a part of everyday life, it may be a struggle to differentiate between killing for necessity's sake versus those who are simply cold-blooded killers. That's a good point this episode tries to drive home, but honestly I don't exactly see it the same way. I can think of many instances where resorting to violence might be the only choice that ensures the survival of me and mine, but that's not the same thing as being a violent person. In the end, I think it all boils down to whether or not the individual has a moral code by which they live. Some do and some do not, so each of us will need to get better at being able to discern the true natures of people we meet.
Another point is the need to be prepared for the necessity of taking preemptive action in order to keep your community safe. In the event of a sufficiently serious disaster or long-term emergency where communities (large or small) may be forced to band together to attempt survival, it is not unreasonable to assume that there will be many threats with which to contend. You must be prepared to deal with issues you discover early on in order to keep them from becoming more serious threats later, and it's important to remember that this kind of preemptive action won't necessarily be limited simply to action involving violence.
