My character was raised as an experiment as a borg by one of the goverments, raised to be absolutely obedient in all matters. When he was in his teens, he got sold to Militech to pay off the goverment's debt and was turned into a "bodyguard" for one of the high level executives, but spent more time dealing with problematic individuals rather than doing any protecting.
Once he turned 20, he got outfitted with a Raven Microcybernetics Ghost FBC for it's ability to blend in with civilians while still having sufficient combat capabilities.
As for morals, he isn't cruel unless specifically ordered to act that way, he spends most of his free time thinking about philosophical questions because due to his upbringing, he's emotionally underdeveloped and essentially a "machine".
I could probably talk a lot about the details of what weapon he uses, which vehicle he prefers and such but I'm not going to since this is already long.
To sum it up, emotionally underdeveloped goverment experiment full borg bought by Militech to kill people who cause problems and spends his time thinking about life and death.
