Harry Potter villain actor Ralph Fiennes is interviewed by USA Today online

Just two days ago, Harry Potter actor Ralph Fiennes
was interviewed by USA Today online.

When describing his role as villain Lord Voldemort,
Fiennes says: "He's really sort of the devil.
"He's completely emotionally detached.
He has no empathy. You find that in psychopaths.
Power makes him feel alive.
It's about power with Voldemort.

I think the HP fandom can agree with this
adequate description of Lord Voldemort.
