Sirius Black
1) He loved James Potter more than any other person in the world. He was like a brother to him and he loved him more than his family (the Blacks) , to him James and the other marauders were his real family. When James was murdered he seriously considered ending his life before decided he would rather end Peters, which he never actually did but still got convicted for.
2) One of the things he hates most about his family other than their love of dark magic and supposed superiority was their obsession of naming children after stars.
3) One of his greatest regrets was never having a family of his own. His other regret which was considerably larger was leaving Harry with his relatives, he would have loved to raise him himself as one last tribute to James. He could have done as well if he hadn't been stupid enough to go after Peter Pettigrew which was the last of his big regrets.
4) He had so many girlfriends in his Hogwarts years because he liked the feeling it gave him knowing these girls loved him, and love was something he received little of especially from his parents. He dumped each one of them after about a week because he was scared that if he allowed them to get too close he would start to love them and then he would be in danger of getting his heart broken.
5) Sirius would never, out loud, admit to be scared of anything.
6) Although Sirius pretended not to care that his parents hated him he did care, and he cared a lot. After all if your parents don't love you then who will? It also upset him that they did love his brother as his one source of reassurance was that they only hated him because they hated children in general and so it hurt to know that it was just him.
7) Moving back to Grimmauld Place was more painful then he ever showed. It brought back memories he would have rather forgotten. In his opinion it was worse than Azkaban.
8) The people he looked up to most were James' parents and he was never as grateful as when they let him move in with them after he ran away from his parents house.
9) Sirius had always been slightly disappointed that his animagus form was a dog as it seemed to emphasis that he was looked down on by his family and that everyone else was better than him. However as it was also the omen of death the marauders had a lot of fun with it. He also enjoyed being big as it meant he had more of an advantage when fighting other animals and when he wrestled James in his animagus form, a stag. Which for the first few months Sirius was jealous of before he saw the perks of his own form. Baby Harry had loved playing with 'Padfoot' also known as 'Snuffles.'
10) As he fell into the veil the person he thought about was Harry and his first feeling was guilt of how his death was going to affect him. After James died all the love he had felt for him transferred to Harry and no matter what Molly Weasley thought, he knew he loved Harry more than anyone else in the whole world.
