It is... one of the banes of society that there will be lone wolves. Isolated individuals. Anyone that does not adhere to the pact of the pack... will be shunned. While wolves might do that for species survival, humans, being humans, do it mostly out of malice.
i'm sure there's an evolutionary aspect for humans as well. diversity can't occur if people don't go off on their own.

in india though, a wandering individual is sometimes respected as a holy man, where as here its not like that as much.
