Why. G I don't own Percy or Harry Potter, I never will. I wish I did, but if wishes were fishes then we could all walk across the sea.

No one ever knew why I did it. Wouldn't let me explain. That's fine with me. If no one ever finds out why I did what I did, I'll be great.

The day I graduated from Hogwarts, I joined the Death Eaters.
Yes, I sacked, and looted, and plundered. Murdered people too. I have the tattoo even now.
Bout no one knows why I did it. Oh they can guess, and they do.
"He was jealous of Harry Potter"
"He was tired of being a dirt poor Weasley"
"He wanted to be exactly like Tom Riddle"
"He was mentored by Peter Pettigrew" That last one is the one they use most often. After all, I saved him from the streets.
Harry tells me that Hermoine still think I was a spy for the Order.
But I'm not. Not a spy.
I did it to save them.
He was going to kill my family. I joined him to save them. Everything I did was for them.
I killed, raped, and stole for them
I even made them hate me for them. I sided with Fudge over Dumbledore
If I made them like me, they'd wonder. They'd worry and I wouldn't be able to help them.
They think I joined Voldemort to be a "prefect that gained power" But I did it for them
For family
For Mom, Dad, Bill, Charley, Fred, George, Ron and Ginny.
And for me.
For Percy
