Choices, Genetics, Demon, or Demons?

I've heard it said many times, "people that are addicted, are so, as a result of poor choices." May I pose three questions?
1. Do you believe addiction is a result of poor choices?
2. Do you believe in good and evil?
3. Do genetics factor in to the equation?
I'd like to approach this topic from both a secular and spiritual viewpoint.
First, let us examine the secular, or scientific (manview) viewpoint.
There has been many behavioural studies on addiction that would suggest a genetic predisposition to addiction is a primary factor in a persons addiction.
There is also sufficient evidence that points to social and environmental causes, when a person presents for AOD (alcohol and other drug) treatment.
For example if uncle Paul, dad and grandpa were alcoholics, then surely little Tommy will be! (Although the gene is supposedly passed on from the maternal side, I would debate any dominance) Fom a sociological and psychological standpoint, I would agree...the family, friends, living conditions, (people, places) play a major role in said topic. Also what a person has endured in their life is relevant. Maybe there is evidence of trauma, whice is causing problems in the present. There could be cause for a PTSD diagnosis.
But, ask yourself, what's the root of the problem?
Let us venture into The Spiritual Realms!
If our belief is that good and evil exists, then the good forces obviously don't favor addiction. While the forces of darkness rejoices when a life, or a family is destroyed by addiction.
But wait! Why are there so many addictions, with an equal number of treatment models and 12-Step based programs?
After 22 years of active addiction and over 15 years of recovery...not to mention 13 years of substance abuse counseling experience...I believe addiction is a proverbial spiritual battle for a persons soul. It's my firm belief, that families with long standing historys of addiction, are generationly cursed.
If demonic power controls addiction, then certainly, there are multiple assignments, or demons sent from The dark one, let us call him Satan!
If there is not, a demonic influence into addiction, then why do so many addictions exist? Food, Sex, Drugs, Alcohol, Gambling, work, bodybuilding, internet, chocolate, perfectionism, just to name a few. It's this wrtiters personal opinion, that there is a powerful demon assigned to every separate addiction, with many imps to carry out their attack on the human soul. There is hope for the broken! For every demon that there is to break us, there is a more powerful Angel to fight for our very soul.
We treatment professionals consider addiction a problem, when a person's life is affected in a negative way, as a result of the use, or abuse of a substance, or behavior.
Regardless of a persons belief system, good always trumps evil; have you never watched the Superhero sagas?
But seriously, think about it on a deeper than human level.
For this writer...It's simple, I was pulled from the pits of hell, by an angelic force, to walk with Jesus Christ, one on one!  Kudos to you if something else has helped you. But for me and my house, I will serve The Lord God with all my being, giving back, to a world I took from for many years. If you, or a loved one is struggling with addiction, hold on, help is on the way.
Blessings!
