I cringe at backstory. Because it never quite explains or gets into some psychological thing that is never quite right and never quite the truth and who knows why someone is some way.
The beauty of 'The Walking Dead' and the beauty of being on a television show for a while is that it's your backstory it's part of what you are it's what you carry with you every day.
Surround yourself with good people. Whether they're the best or not people are capable of learning if they've got good hearts and they're good souls.
