"Say, ever since I've met ya, ya've been wearin' that tattered old scarf. Does it have any kind of significance?"

"This scarf? Of course it does. It's my shackles. It ensures I can never escape the memories and the consequences of my sins"

"Damn, son, all that from a scarf?"

"But of course. It was given to me by the one whose life I ruined, after all."

Because nothing says "crippling self pity" like a tattered old scarf, amirite?
