Strange Man (Lucifer or Devil) in RDR2

There is a Strange Man with special powers in Red Dead Redemption 2. Strange Man is an immortal being that has cabin located at Bayall Edge in Red Dead Redemption 2 (RDR2). He is also known as the Grim Reaper, Lucifer, or Devil when you look at clues given. Herbert Moon is a person who made pact with Strange Man, and asked for two generations (free from curse) instead of happiness. This indicates that Herberta Solomons (his daughter) is the second generation and Herbert Moon is the first. Video below shows all the different stages of the Strange Man Painting from beginning to finished product. After finishing (by visiting the cabin every 5 days), the Strange Man can be see in a reflection of the mirror. Video also shows a camper near Armadillo talking about the curse (like Cholera) on the town and the grim reaper (devil) with a top hat responsible for the outbreak on Armadillo. In addition, video shows all the wall writings, desk carvings, and paintings relevant to solving the mystery. For example, the paintings in the room will change from Elk to coyote if you have low honor. Little surprises will also be revealed like if you take a picture of lucifer's cabin it will have indicate serial killer in the picture, and there is a dead alligator underneath the cabin. Jimmy Brooks also appears as a name carved on a small table (from mission Polite Society, Valentine Style). Later in the video, you can also see the grave of Herbert's brother (Francis Moon), and the hidden changing room on second floor of the general store in Armadillo.
