Before Joker Lost it he was an honest man trying to get some money for his wife & (unborn) child.
So he decided to unisciti The Red- cappuccio gang.
But on the night he was meant to start , he found out his wife and child had died.
But the gang didn't let him leave so he was forced to do it.
Inside an aced factory , he was made to fight Batman.
Then he tripped and fell into aced.
In " Suicide Squad" he stated that after electric shock therapy , he was left in a black hole of anger & memory-loss.
He forgot his wife but HATES feeling love.
That's why he doesn't Amore Harley. But still feels something...
( P.S. I got the info from Batman: killing the Joker / Suicide Squad.)
