The sins of a poor family

Pride
He used to take such pride in his appearance. When he moved out he started to make decisions about his appearance for himself, much to his mother's chagrin. He grew his hair out and pierced one ear. Both earned multiple arguments from his mother, but he didn't care. He glanced in the mirror wistfully and gingerly touched the scars that marred his once beautiful face. His mother didn't complain about those, at least not to his face. There was nothing about his appearance now to make him proud.

Greed
He stared at the empty seat where his brother should have been, and for the thousandth time blamed himself for his brother's death. His greed had driven him from his family; he turned on his parents and siblings, and tried to turn them on the boy who was almost part of the family. When he finally saw past his greed, it was too late. He came back and his brother died. His greed made him pay.

Envy
He had never really been envious of those with more than him. He knew that his family didn't have much in terms of money, but they had each other. What more did they need? But watching his children suffer because of him, made him envious of others. Every time his boys got teased because of their hand-me-down robes he wished that he had the means to buy new ones. When Potter gave his youngest boy lavish gifts for Christmas and birthdays, he wished that he could do the same.  But envy would never give him anything.

Sloth
He didn't move much these days, he didn't see the point. He used to be full of such life, but now he only thought of death. He used to never be alone, but now he wanted no company in his solitude. His energy died with his twin, leaving only an empty shell.

Lust
She had been in love since the day her brother left for Hogwarts. She listened to stories about the boy all year, from September until when the boy showed up at her house. Loving from afar is easier when your crush isn't in your house. She had suffered endless teasing from her siblings about her crush, and endless advice from her crush's female bestie. Eventually she tried to get his attention through jealousy. She dated a friend of her crush's, and hoped that he would melt in her hand. Finally, she got what she wanted…until he left. All her lust got her was a broken heart.

Gluttony
He had loved food for as long as he could remember. At first, his mother's food was the best in the world. Then he tasted Hogwarts food, and his love expanded. His first trip to Hogsmeade, Honeydukes in particular, expanded that love yet again. But he wasn't just a glutton for food. He loved danger, or at least he was used to it because it happened quite a bit. Then he met her, and she smothered him, literally and figuratively. All she wanted to do was kiss him, which pissed off his friend, until his beloved food got him in trouble with his girlfriend. Now she's mad at him too. Turns out he's a glutton for trouble.

Wrath
She wasn't mad all the time, just some of the time. But then, a temper is probably required when you're the mother of six boys. She was the worst thing you could threaten her boys with. She was also the first person they would come to if they were in trouble. She resisted the urge to snap at the annoying blonde who was trying to take over her job of caring for her boys. She looked back at her son who lay bleeding on a bed. White hot rage reared up inside her as she looked at her mauled son, but she could do nothing to the monster at the moment. This left the rage to boil up inside until it turned on her. She blamed herself for not being able to protect her son.
