My friend wants to kill people. This song is for him. Its a long song but if you can read it tell me what you think.

Killing is an art

I have a lust for blood
I search for my high
Tell myself its the last time
But I know its a lie
Sharpen my blade
Voices ring inside my brain
Each and every death
Brings me closer to fame

I have a lust for vengeance
Don't ask me twice
I have no mercy for the weak
With strikes so precise

More blood for the walls
More blood for the walls

Killing is an art
And I need to perfect
My style is to slash
My means are Misdirect
I am painter
My favorite colour is red
Killing is an art
And I wont stop till I'm dead

Run with all your might
Your effort will be mislead
I will chase you down
Until my addiction is fed
Don' bother begging
It makes me want it more
I have my trusty blade
ready to stain the floor

I have a lust for anger
I love a good hunt
Its not just a sport to me
I'm one you don't confront

More blood for the walls
More blood for the walls

Killing is an art
And I need to perfect
My style is to slash
My means are Misdirect
I am painter
My favorite colour is red
Killing is an art
And I wont stop till I'm dead

I am in the business of murder
And business is good
There is no limit to my hunger
If only you understood
We are all animals inside
Our inner intentions are cruel
If you say your better
Who is the bigger fool

We kill each other over religion
Flag and country too
Whats the difference if I like it
There's no point being untrue

More blood for the walls
More blood for the walls

Killing is an art
And I need to perfect
My style is to slash
My means are Misdirect
I am painter
My favorite colour is red
Killing is an art
And I wont stop till I'm dead

we are all killers
We kill the land and sea
When you hear someone knocking
You better hope it isn't me

I liked most of it, though I think a few bits could be improved.

'I have a lust for blood
I search for my high'
I think this part may flow a little better if you change it to 'I lust'. The same goes for the lines 'I have a lust for veangance' and 'I have a lust for anger'

On this line 'Voices ring inside my brain' I would suggest using 'voices rise inside my brain', I think it would give more of a feeling that the 'voices' are getting louder, driving the person to kill.

'I have a lust for vengeance
Don't ask me twice
I have no mercy for the weak
With strikes so precise'

In the other parts similar to this the starts of the first two line are 'I', I think perhaps you should follow suit with this part.

'I am in the business of murder
And business is good'

I don't like these lines, it seems like you just changed the wording of 'Killing is my buissness... and buissness is good', I'd like to see something different there.

Well thats all I have to say, hope I helped in some way.
It didn't take long to realise
The safest place was not her arms, but her eyes
Where she can't see you
For her gaze, it blisters;
Grey skin to cinders
