So I just created a new character. A rather angry Orc barbarian who kills everyone he possibly can. I just slaughtered most of the town of Riverwood as soon as I got there, failing the "Talk to Gerdur in Riverwood" portion of the main quest. I was sadly unable to kill Lucan and Delphine. I'm just wondering if this unorthodox playstyle is workable throughout the entire game?

To be fair, play that character with a dead is dead play through.

Too late for that, Alvor already killed me with a warhammer during my first seige. I immediately attacked him first after I reloaded.
