So basically this guy was a member of a gang of outlaws, they were as brothers. Close like a family, until Dex joined. Dex saw the large bounty that the leader had put on him, dead or alive, and figured he could also make some extra money from the criminal activity that they were partaking in (Dex was already a criminal at this point.)
so one day, Dex saved the leader of the gang's life in a bar he was known to frequent during a brawl,
and he's accepted into the gang. During a bank robbery gone wrong on Denon, he and the leader were separated from the rest of the gang by [insert contrivance here] and Dex took the opportunity to blast him in the back of the head while he wasn't looking.
He escaped, and later turned in the leader's corpse to the authorities.
In terms of personality, Dex is a brash, arrogant criminal who will betray and backstab anyone or any group to get what he wants. He doesn't care about anyone else besides numero uno, because that is what he believes is most important in the galaxy, your own survival above anyone else's. He is not an honorable man, if you engaged him in a sword duel he would probably pull out a blaster and shoot you.
