Amigo Ou Inimigo? (Animes)

It's just that in reality I can't deny it anymore
I can't take this, I just want to give up
They just tell me they will take away my peace
I have no idea how I ended up here
Only I know the true pain this brings me
My soul shivers just by hearing
This sensation has become too cold
And it's in this internal war that they ask to leave

I think I'm going to surrender
And let you take me
I'm tired of fighting
I know I won't endure
Yeye, so do as you please
Just end this pain and I will yield
Just as you want

I became a killer
I am a hungry monster
And I feel
That this time I won't be able to control myself
These voices say there's no harm in killing
Friend or foe?
Just make them bleed
See the pain in their eyes and make them scream
Feel the despair watching the prey cry
Is there something worse?

Maybe it was the love I didn't have
But I already know what it turned me into
It controlled me, dominated me
And wanted to take possession of me, now everything has changed
I only feel hatred
I don't know my desires
This being that took over me now only wants to hunt
I don't remember anything anymore
And only return to consciousness
I just think someone here needs to stop me

And I'm killing
Even the enemies are dying
Because, man, I'm too angry (wooh)
And these demons inside
Already knew they were rivals (wooh)
So just listen to me, please
I just wanted you to stay away from me
Didn't want you to see me like this
You know this face?
This is not me, it's just a dark side that dwells in me
That's the truth!
And if I distanced myself it's because I know he's still here
I miss
And if it's like the last time I accidentally hurt you?

Then step back
Then step back
Then step back
Just go back to being who I am
I just wanted to be half of me
I don't know what this turned me into

I became a killer
I am a hungry monster
And I feel
That this time I won't be able to control myself
These voices say there's no harm in killing
Friend or foe?
Just make them bleed
See the pain in their eyes and make them scream
Feel the despair watching the prey cry
Is there something worse?
