Thank you so much for finding it!!! YOU ARE THE BEST!!!

Hi: I'm looking for a fic where Dumbledore sent Harry away to a school for training after fourth(?) year. He was at this other school for two years before being brought back. His nickname or code name from the school was 'Sinful' or 'Sin' for short. It was also tatooed on his arm. He ends up killing the Dursleys and joining Voldemort as his Heir... I think Snape is on his side and Harry was also drinking blood in one scene at Grimmauld Place. His two years away were difficult and he had tried to kill himself at school at one point. Any help in finding this would be great! Thanks.
