There was a lot on Marcel's mind as he drove to see his father. Honestly, when that news came, Marcel had somehow hoped that the man was dead - at least it would save him the trouble of finishing the job himself - but at the same time, a tiny bit of him hoped that he was okay. And it was that tiny bit of him that he resented so much.
His father was right, he was a weakling. He had gotten his compassion from his mother and that emotion would be the death of him. Look at him, he had a girlfriend who was keeping the secret of another man that was also his enemy from him and yet he kept her alive. As if that wasn't enough, he couldn't protect his sister enough. And the cherry on the top, his father was a thorn in his side, amazing right?
He was pathetic.
