Why does Jim and his mother go to the neighboring hamlet?

At the death of Billy Bones, Jim immediately tells his mother everything about the strange men and the two quickly realize that they are in severe danger. Even though they are owed some money because of Billy Bones extended stay at their inn, the two decide to leave immediately in order to avoid encountering Black Dog, the blind man, or other despicable characters. Although the most prudent idea would be to get Dr. Livesey, Jim does not want to leave his mother alone and so abandons that thought. Instead, the two decide to seek help at the local village.

Well, when Jim told his mom everything they were frightened and didn't know what to do, if he went to see the Doctor Livesey as the Captain had told him to do he would have to leave his mother alone and her safety was his priority and also it seemed too dangerous to stay at the inn, they finally decided what they ought to do, First going to the nearest village to get help and then would come back to the inn to take the money that the Captain owed them
