True Friends

It's been edited a lot. I won't lie, I've cut out about 1/3 of it. But that's because the first part was really quite stupid.
I wrote it a while ago when my friend was being stupid. Then it kinda morphed into this totally unrelated poem. So yeah. R&R, please.
Oh, and it's all stuff that if you think about it, can be done with a knife. ::yes:

Edit: On request, the edited part that hasn't been lost to fire will be put up in
unbolded font.

This is a fatal attempt
To let you know what's here.
What's going on right now.

And right now I know
That by the end of this
One of us is going down.

I could dance around the subject,
But what's the fun in that?

Draw a knife of your beliefs.
Cut it out; What do you mean?
Hate stabs people in the back.
Mercy saves, and that is fact.
Human envy, lust, and pride boast
They'll slit you right across the throat.
Pity cuts a person's pride.
If it's your own, you'll bleed away life.
One thing I've learned, and learned it well,
Keep it safe so you may tell
That with a knife not very blunt
True Friends stab you in the front.
