[Zalge]

You can kill me if I'm doing this wrong.

Riddle1: (this one is the most obvious one ever...)
I join you in a place filled with light
Alongside you, I swore to fight.
But what I was was really a mask
All to hide my evil task
I worked for one of your rivals
only I could foresee his arival.
I left his company and now I see
What I did truely disgraced me.
Who am I?

Riddle2: (slightly tougher, but still easy)
I was sure that we were friends
I wished that it would never end.
I felt feelings you did not see;
I didn't know how you felt for me.
Death greeted me with open arms
because of all the people we did harm.
I stood there staring as the 'sky' fell.
Sending us all straight to hell.
Who am I?
