Im writing a fantasy/sci-fi book about the 7 deadly sins.so i need some Deadly names?

Ok so I'm writing a book about the 7 deadly sins. And each sin is going to be a person in my book. So I need deadly names for these people. It will be 3 girls and 4 guys. I need like names that remind you of something horrible or really weird names that you can't pronounce. Thanks so much!!!!
