Ok, so he's got the cliché "Tragic Past" of 90% of all fictional characters.
Liz: There's no need to be sarcastic.
Dagless: Maybe if everyone who'd ever been close to you had died, you'd be sarcastic, too.
Liz: Yes, that makes sense.
Franky: You gotta admit, that was nowhere near as bad as Chinatown, boy that was-
Goon: Franky, don't even bring up Chinatown.

Don't you just love to read pointless and poorly written garbage about fictional people's problems?
Well if you do you're a complete sadist but that's okay, you've come to the right place. This is the land where we step over the borderline from "tragic past" to "Loaded up with so many problems it's kind of sick". Sounds like fun huh?
Take a glance around the room and you will see our first victim. His name is L Lawliet. Although he possesses legions of adoring fans they all seem to be obsessed with torturing him. Let's take a closer look.
L sat sadly in task force headquarters. He felt his imminent doom hanging over his head as well as the pain of his unrequited love for unnamed love interest/dead love interest. This reminded him of all the tragic things that had happened to him, the things that kept him awake every night for fear of terrible nightmares (because this explanation of L's insomnia isn't complete rubbish at all).
He thought back to his childhood as a poor orphan boy. He thought about that flashback he was going to have later in the series when he died and how it showed how tragic a character he was.
It had all started when the young boy had to watch his family be brutally murdered. They were shot/burned/eaten/poisoned/exploded/forced to watch the Pokémon movies. It was a horrifying memory that would haunt the detective all his life.
After many heart-breaking scenes of carnage Watari brought the young L to Wammy's house. He was very emotionally scarred and had no friends. Then one day Watari brought two new children to the house, A and B.
L immediately fell in love with A/B/random other chick. Unfortunately they died. All of them. Violently. While still carrying his child. Right in front of him. Other wretched stuff.

The past is a gaping hole. You try to run from it, but the more you run, the deeper, more terrible it grows behind you, its edges yawning at your heels. Your only chance is to turn around and face it. But it's like looking down into the grave of your love, or kissing the mouth of a gun, a bullet trembling in its dark nest, ready to blow your head off.
— Max Payne, from Max Payne 2
They were after me. It was my fault. You can't run from your past. You'll end up running in circles. Until you fall back down into the same hole you were trying to escape from, only the hole's grown deeper.
