Is your character a thief named Rachel?

I'm having a crisis of conscience. I've been asked by a disreputable scoundrel to do something that will cause an accident that will provide a lot of loot and gold. Before I could follow through, I entered town and everyone is complaining about this scoundrel and the trouble he causes. So now if I help him, it will directly contradict values I hold dearly in real life. But it's a game, so why shouldn't I do it, especially if it means making a lot of gold?
