If it wasn't already bad enough, with the rise of the the Empire the the situation for those ''below'' normal society only worsened. Often fighting to survive, to eat and to care for themselves and their families.
Motivation
Adrenaline fuels this person to do what he does. He is ADD. Forever living ''on the edge'', he strives to live every day like it's his last. (And, considering his choice of life stile, any day COULD be his last) He does mean well, but sometimes his recklessness gets on peoples nerves. Always looking for a job that pays pretty well and allows him to blow some stuff up. Plus, he likes helping people. Sometimes.
Obligations
Addiction. Always needs to have some sort adrenaline coursing through him at all times. Where he gets his ''fix'' doesn't mater to him. Whether it be from defusing a bomb, saving a persons life, doing something dangerous or playing ''chicken'' with some friends, he just needs to feel the ''buzz''. This can cause him to be reckless at times, but he doesn't really care.
