My name is Hanzo Hasashi. No longer will I be known as Scorpion. For centuries, I have been enslaved to my anger, imprisoned by vengeance and embittered by my bloodthirst. I have made enemies of all Humans and spirits alike... No more. I have chosen a path of freedom... And I will follow.

........................................................
Almost a year after I've been set on this path by the warrior Nightwolf, I met the woman who I fell in love with... Utsukushi-sa (she preferred 'kushi') With her, I had a son, Kanji. It was the perfect path I had chosen. Peace wasn't far from me.
.............................................................
"Kanji... Kanji!" That was me calling out to my son. He was nowhere to be found. I asked kushi. She too was perplexed. Once again, I checked his room... There was a note on the wall...
"Chichi... Anata no michi o miidashita yō ni, watashi wa tabi o shite watashi o mitsukemashita. Karera wa watashi ni ima okotte iru koto o anata ni tsutaetai to omotte iru monodesu. Shikashi, watashi wa dekinai. Gomen'nasai.                                 Kanji"

Translation

Father... Just as you have found your path, I have journeyed to find mine. They are things I wish I can tell you now, things happening to me. But, I can't l. I'm sorry.
                      Kanji
......................................................
Smoke, fire... The clan was burning. Kushi was dead. In my attempt to escape. I was captured. The leader of the raiders came towards me... I immediately recognized him...
"Kanji?"
"Kanji is dead." He said in a hoarse voice "...my name is Akuma!"
.............................................................
How I escaped, I don't know. The only thing I know is I have been set back on the same path I once rejected... Vengeance!
