By the time addiction has become truly problematic, a person will come up with a bunch sophisticated defense mechanisms to continue feeding his/her addiction. One of these defense mechanisms is playing the victim role.
Why do addicts play the victim?
Knowingly playing the victim role helps an addict to control and influence the thoughts and feelings of others, most commonly parents and spouses. An addict hardly copes with their actions — they’re ashamed or afraid to acknowledge this and seek help — so they justifies their actions as a way of controlling the situation.
