I like the character concept as a whole, but the beginning of the story seems a little bit contrived. (He wanted to slaughter the village to please his dark god but couldn't.)

Some development into other motivations to destroy his hometown, (perhaps humorous ones,) how he came to know the god of slaughter, how he became a bard, and if his original mentor was a good bard, or a master of death metal would go a long way with fleshing out the character's personality and motivations.
