Private
I suppose you could say I sold my soul as well... to vengence. I thought my family had been killed by Lycans when I was 19. I became a vampire to join the war against them. At least I found some of it again when I found out the was was built on lies and began my campaign to end it.
At the first hint of such actions, the entire Department will come down heavily on the perpetrators.
Classical music? Of course when I learned much of it, it was a contemporary art form. I did learn jazz piano from Jelly Roll in 1920s New Orleans, and have since gone on to rock and roll. It passes the time.
So you tormented souls consigned to hell for their actions while alive? It sounds more like a job description than anything else. For over half my life, my job was to kill people and break thing, and I was very good at my job. But none of that seems to matter here.
