GLUTTONY- SIMON
If there was one thing that Simon hated since he became a vampire, was the constant thirst for blood. Ever since that day. He felt this burning sensation at the back of his throat that could only be calmed with the taste of blood. And not just any blood; he needed the warm and juicy blood from a human being, not the cold one that he could war up in the micro or animal's blood. No. This wasn't Twilight, where animal blood made everything okay. It made everything harder, because animal blood was just a replacement of the real stuff. The real, juicy, red, and tasty stuff.
He blamed it on Jace. If he hadn't given him blood that day on the boat, he wouldn't know what blood from a living human tasted like. Then again, if he hadn't done that, then Simon wouldn't be "alive" right now.
Then he tried to blame Isabelle, for offering her blood to him. He was getting better at controlling his thirst (or so he told himself) and then she came and told him to drink from her! The woman was practically asking for him to kill her! He gave in, and miraculously stopped. He felt guilty for that because he enjoyed it when he shouldn't have. Deep inside, Simon knew that it wasn't Izzy's fault; it was his for giving in. His for being weak. And his for craving blood.
Simon knew that the rest of his immortal life would be like this. Till the end of time, he would only be a blood thirsty beast with an unending crave for blood; that was the truth. It had always been the truth. There was no way to change it.
