Many people with addiction problems can get over them in time. But combined with Chris's violence and Mob connection, he never really had an incentive to clean himself up. It would, in the end, have required him to drop the Mob life, too.
That's pretty much the bottom line on Christopher. Any decent therapist or addiction counselor will tell you that you'll never be able to live a truly sober lifestyle if you're mired in a "toxic" relationship, friendship or environment. You can't get more toxic than the criminal life. Ironically, Chris's two minute window to get out would have entailed him getting into the car with Adriana on that fateful day and going into protection. And in that scenario, the self hate that a rat has to incur would probably just lead to more alcohol and drug abuse in his life after leaving the mob. Just look at Henry Hill. The guy is still getting arrested once a year on drunk and disorderly charges, and he's almost 70 years old. So as Capo pointed out, yeah, he almost gets a pass for the way his life ended up. Almost. Beacause in the end, we're all accountable for the choices that we make.
