I'm not so sure about what you said about them being losers and rejected by society. Every report I've read (yes I know, if it was reported in the media it's probably the exact opposite) said that they were outgoing, had lots of friends, and well liked.
**edit** I guess I should clarify, the younger one was described that way. The older one claimed on his twitter page or some other social media that he doesn't have any American friends and doesn't understand Americans.
