This Index Has Had a Hard Life

"It's a hard-knock life for us!"

An index about characters who have had a hard life, the things that happened to them, and how such things have affected and continue to affect them.

See also Madness Tropes - a tragic past can lead to mental disorder, but not all characters who experience tragedy go mad, and not all madness is the result of a tragic past. The former goes here, but the latter does not.
