Interpretation of Robert Frost's poem "Design"

"Design" poem by Robert Frost:

I found a dimpled spider, fat and white, 

On a white heal-all, holding up a moth Like a white piece of rigid satin cloth-- 

Assorted characters of death and blight Mixed ready to begin the morning right, 

Like the ingredients of a witches' broth--
A snow-drop spider, a flower like a froth, And dead wings carried like a paper kite.

What had that flower to do with being white,
The wayside blue and innocent heal-all? 

What brought the kindred spider to that height,
Then steered the white moth thither in the night?
What but design of darkness to appall?-- 

If design govern in a thing so small.

Comparison:

               Here we can see that how our thoughts are always being unreal. In poem there is the reality and truthness of life, struggles, symbols ,fall of life and death. The symbol of beauty is whiteness but here we can see how the white colour seems very dangerous or very frightful. The natural cyvle of life and death is there. Robert frost gives the example of the whiteness thretens the life. In the poem a white heel-all plant is the place  and white spider and the white moth. Here the natural things are shown in one colour white. In the reality there are no white plant,spider or moth. How the spider kills moth very pridictively. Moth dies slowly with so many struggles. Here is the idea of witches. Its symbolise the death or villain element. Horror image and black magic and all. Spider as a witch and broth as a dead moth.

Other example of whiteness,witch and war between truth and lie are: Harry Potter- lord woldmott as a element of witch and another is Narnina- white witch as a villain

                 At the end Robert Frost brought some questions.
Is it real all things or not?
If yes then why?
The difference between reality and fakeness are here.
The design of the nature is natural or artificial this the question.

Classroom activity:

                  As per our classroom activity we have done drawing of nature. This is the example where we can see that the real natural designs are brought or not. The two faces of natural cycle are life and death. So in our mind we only want to stay with life not with death. In the drawing we can see that we are not ready to accept the reality. Beacause we don't want to see death. The design of the drawing is also the question.
