Where had we gone wrong?

In the summer after Sirius' death something terrible is about to happen at the Dursleys and Harry deals with the problem in a different (and violent) way. After that he receives the visit of two Death Eaters. Of course none of this can be good. Or can? Warnings: Dumbledore/Molly/Ginny/Ron Bashing, 'sane' Voldemort, torture, violence, Dark Harry, Dark Hermione, lots of OOCness.
