 In an interview with MTV News , Bernthal stated that Walsh was suffering from the " loneliness you feel when you 're right there with them and you can 't be with them in the way you want . " Bernthal applauded the writers for such changes , and felt that the storyline never <unk> . " The people that Shane loved more than anyone else in the world before the apocalypse are still very much alive and still very much with him , but he 'll never be with them in the way he wants to and the way he once was . Every relationship — Shane / Carl , Shane / Lori and Shane / Rick — it 's tainted and fractured . When you suffer from that kind of loneliness , it brings out the worst in you . "
