where in the book it states that Tom and Huck perceive their biggest struggle between themselves and Injun Joe, whose gold they want and their afraid that injun joe will kill them
"Injun Joe repeated his statement, just as calmly, a few minutes afterward on the inquest, under oath; and the boys, seeing that the lightnings were still withheld, were confirmed in their belief that Joe had sold himself to the devil. He was now become, to them, the most balefully interesting object they had ever looked upon, and they could not take their fascinated eyes from his face. They inwardly resolved to watch him, nights, when opportunity should offer, in the hope of getting a glimpse of his dread master." Ch 11
