Sinful life in DC universe

Abnormal is a word you could summarise my entire life from the day I was birth to the moment I died, My Father was the head of a well-known Mafia organization, Something I wasn't proud of but beggars aren't pickers I sort to change the whole thing but what could I do, I wasn't a child of his main wife so my life was filled with hardships from birth my mother crumbled and committed suicide after she realized there was nothing she could do to help or change my fate to be a stepping stone for my brother.

Numerous years later I won after the continuous killings, Stealing my brother's wife, and Assassinating my father I managed to change my fate or so I thought in the end I died of heart disease it was surely the end for me

But Why Am I Suddenly A Hencemen In The Joker's Legion?
