He is a dictionary definition of evil. Everything is all about power; that's how the world works. Past this world, however, Voldemort is screwed! He attempts to solve the problem by hiding bits of his soul all over the place so death can't take him where he needs to go.
I like how Voldemort, fearing death, has attempted to overcome it by putting on the Grim Reaper costume. School pscyhologists say kids with a fear of vampires or robbers should put on, for example, a vampire costume on Halloween and be a vampire. Oddly enough, this has helped children (age of 5) banish fears they have developed from watching a horror film or having a bad dream. The children report not having that particular fear after wearing its costume. It's funny; it looks like Voldemort is trying to do the same thing.
