At the time of writing, this story is scored at 5.57; that's a travesty. I know why it's scored that way, it's because it's a dark story to start with, and it doesn't end the way many readers would wish. There's very little sex either, but the amount of sex in a story shouldn't determine its quality.
This is a powerful story, and the message it carries is heavily underlined. Hate is corrosive, and ruins everyone it comes into contact with, the true opposite of love isn't hate, it's total indifference. This story is about what happens if you follow the former path.
This is powerful stuff, you may not enjoy it as much as some of the more pornographic, or saccharine offerings on SoL, but if you don't read it, you'll be the poorer for it.
