Warwick's Past, Present, And Future
The Past
Warwick taunting Jinx
"You were there... "
"Let me forget... " 
Taunting Vi
"The fear in your eyes. I've seen it before." 
What we know of Warwick is he was some kind of career criminal.
Though many think of Warwick as no more than a beast, buried beneath the fury lies the mind of a man - a gangster who put down his blade and took up a new name to live a better life. But no matter how hard he tried to move on, he could never escape the sins of his past.
I'm going to hazard a guess that Warwick was doing wetwork, and Jinx and Vi's parents were probably murdered by him right in front of him. And who knows, maybe it was seeing them (individually, or together) that changed him. Or.....tinfoil hat time what if Warwick for some reason killed his OWN family or someone close to him, or began to and Jinx and/or vi were his children, or children of one of his friends?
The Present
Warwick is a sort of vigilante anti-hero, hunting Chem-Barons and their lackeys. He follows blood wherever it is spilled. But in his color story he loses control and doesn't even know if he saved the girl or killed her too. This sort of begs the question....what was Singed plan in all this? Was it just a 'see if you can' and never mind if you should?
The Future
Where will Warwick's story go? What if Singed's augments fail or break down; will Warwick live or die? Would destroying the augments free him from his blood rages?
Since he is half wolf man does that mean he had distant Vastayan blood or that it was used in his creation?
