Very interesting contrast created in this episode between the Rick and Shane characters in how they treat outsiders. Remember that Shane killed Otis—not an outright "outsider", but perhaps best considered an "ally"—for the survival of what he considers to be his "clan". He is not concerned for what is best for the group, only what is best for him, and for Laurie, and for Carl. Rick rescued a "hostile outsider" from certain death—in so doing, he probably jeopardized the continuity and survival of the group. Shane's choice was insular and short-sighted. Rick's choice is a massive gamble, but with potentially huge benefits: his act is a commemoration of humanity in what is becoming a dangerously inhuman world. For all his bluster about keeping the group safe, Shane is proving more and more to be a coward. His methods may prove to be temporarily successful in keeping the group physically safe, but on some level—and with a lot of help from Hershel—Rick is demonstrating that humanity is lost when compassion disappears. His actions stand in brazen defiance to the zombie "new world order".

This speaks to a major theme in the show: how do the characters survive in the new world, and how will it change them for better and for worse? Dale was right in pointing out to Shane that he "belongs in this world" in Episode 2:5, "Secrets", but ultimately what good is survival if they must sacrifice their humanity? Rick's reciprocally outrageous act of compassion helps to ensure that humanity and dignity triumph.
