Pride.

What exactly is Pride?

Pride is excessive belief in one's own abilities, that interferes with the individual's recognition of the grace of God. It has been called the sin from which all others arise.

Now, I may not be a godly person... but this boy drives me crazy with his pride.

He thinks he's better than everyone else-

He thinks he's the best Quidditch player at the school.

Yes, I am talking about Head Boy, Slytherin Captain and Seeker-

Draco Malfoy.

Since he was doing guards around the school, and I knew where, I waited in a silent, deserted spot where I knew only he would walk through.

When I saw him approaching, I walked into the open, a smirk on my face.

"What are YOU doing out of bed?" Draco said directly to me.

"I should be asking you the same thing..." I told him.

"I am Head boy, I am allowed to be out after hours but you arent.." he smirked.

"50 points from-" He started as I took my wand out and pointed it at him

"Petrificus Totalus!" I summoned.

I watched as his legs and arms bind together, then I used Mobilicorpus to get him to a deserted classroom and put him on a table. I took out my wand once again, pointed it at him as he was waking up.

He looked at me.

"200 points from-"

"Cruciatus!" I said.

He closed his eyes and gritted his teeth together in pure pain, I just smirked.

He began to take out his wand, when I pointed my wand at him one last time...

"Avada Kedavra" I said, the spell hitting him.

I watched him close his eyes for the very last time. After that, with gloves on, I ripped his shirt and robe so his chest was showing... I was very disgusted with this... and took out a pocket knife and cut into his chest

"SIN NUMBER ONE- PRIDE"
