One of the walking dead forums had this long post about the guy and how he figured out the cure to everything and he was trying to get someone to stop so he could end everything.
Also it was said that at the end of the show when Rick said he was seeing things they thought because no one said anything about the guy maybe Rick wasn't sure he thought the guy was real.
Anyways group or no group he still would have understood that his actions would get him killed or everyone killed by drawing the attention of the zombies like that. Hell maybe that is why is he doesn't have a group anymore
