Quicksand

[Malu]

I have accepted the darkness into my soul
I accept that I am a dark man
Darker than you Prove it
Will there ever be light in my life? Light opposite of dark, nothing new here, what kind of light?
This stanza had "darkness" "dark" and "darker" I think you could use more vocabulary

The light scares me How and why?
It empowers my sword weakly Would you like a blue pill? It might add some color to this.
I must remain in the darkness
My friend, the darkness These last two lines end with darkness...

What kind of darkness? I don't know, you only said it numerous times already
Do I dare tell the secret?
It's hard to say
For it is utmost evil Darkness=evil. That's a given.

Quicksand
That's the dark source And?
Girls in it
Do you judge me?

Masturbation
To the darkness
Sustains my true aura
My true self

I have shared with you my secret This is a statement, you already told us the secret, no need for reiteration
Do not judge me You asked if we judge you, and now you say not to judge you. Interesting.
For I am just a man
A Dark man I dont think you need to capitalize dark, it's easy to tell that this poem is centered around that

Interesting metaphor. You said darkness, dark, and darker a total of nine times, that's way too much. All that does is take away from the meaning.
