Is it really such a sin?

[Hollywood]

Hi, I'm new and I'd like to introduce myself. I am a 16 year old male, my name is Vince and I love to write poetry in my free time. This was the first poem I ever finished and I would like to share it to receive suggestions and criticism. I currently suffer from depression and I never can think too straight so most of my poetry is dark (as is this poem). You can pretty much guess what it is about. Please give me your thoughts

     Loved you see,
A weakness for he,
You take advantage,
to hearts you do the damage,
So don't blame me,
if I don't hear your plea,
For when I kill you see,
My eyes a devil in me...

Lie with me tonight,
Your death won't be such a fright,
As I put on my mask,
and feel the cold of the night,
My devil leads my task,
I'll slit your throat - don't talk about him,
Your life - This night - such a dim,
I see the beauty in you,
Oh yes baby I do,
Your death is what's best for me too...

In hell we're together,
We'll burn in this weather,
Our ashes spiral and tether,
It's love - can't you see,
Yes the devil wins,
But together we'll be,
So tell me, is it really such a sin?
