Why does NARAKU NINJA wish to slay other NINJA?


DŌMO, I am SENSHIN.

Fujikido Kenji's NINJA Soul is that of NARAKU NINJA, a NINJA who wishes to
slay NINJA. And thus, Fujikido becomes NINJA Slayer. I understand why Fujikido
wishes to slay NINJA - his family was killed by the NINJA of the SŌKAIYA, so
of course he would want to perform FUKUSHŪ1.

But what is NARAKU NINJA's motivation? What drives him - a NINJA himself - to
slay other NINJA indiscriminately?

1 Note: FUKUSHŪ means REVENGE.
