How Did The Brother Plan To Kill His Brother?

In my version of the story, I had the older brother plan to kill his younger brother. The older brother was planning to kill his younger brother because he was a burden to him. The youngest brother never intervened with his older brother's life or popularity, but it bothered the older brother. This led to the older brother to plan a murder for his brother. He hid a shovel in the forest and went out early every morning to dig a deep hole to put his brother in.

In the town, there was property damage and animals were being killed. This led to the younger brother to volunteer to search and kill the beast who was doing so. The brother was trying to show to the town people that he could also be the hero of the town and this would gain him admiration
He then realized his brother was planning to kill him, but he ended up killing him before he had the chance. The older brother was digging a hole long before so he could kill his younger brother and put him in it. He devised the plan of the beast terrorizing the town so he could venture out with his brother to hunt the beast. This is why the beast reference for the older brother is important because the beast always hunts its prey hence the younger brother.

Now the younger brother was not afraid anymore and decided to take his brother's place. When he went back home a few people and his brother's wife were at his door wondering if he knew where his brother was, he replied with, " I know nothing, what am I, my brother's keeper?"
The term my brother's keeper refers to the bible when Cain and murdered his brother Abel, and when God asked him where his brother was Cain replied, " I know not; am I my brother's keeper?"
This is important because one of the brothers was favoured by the people, but the other was not which led to the motive of planning the murder. The motive for Cain and the older brother was jealousy which led to their
