This is a hard question as there is no way of testing it in my own life going back. I do believe that if certain complex parts of my history had unfolded differently, there might have been a lower risk for me to develop a serious addiction. It is not related to one or two people though and I doubt anyone could ever had an influence on me stronger than my addiction. There have been elements in my life though that I felt very attached though (not people in my case) that provided strong motivations to get sober and not to destroy everything, more than once. But they did not prevent me from sliding into the addiction in the first place. For me this is not about a sane view or protective good will, more one attachment being strong enough to interfere with the other, and none of them were related to people primarily and both had strong obsessive elements.
