People who are prone to addictions of any kind, what keeps you going knowing there are grave consequences in what you do?

Humans are complex beings, our minds work differently especially social wise. While in the animal kingdom addiction is.. most certainly uncommon humans adapted the trait and its downsides as you said before. That being said in my addiction.. knowing the risk of everything i built up, it's worth it to hear her say "i love you". Sure she might not always be there when i need her, or is stupid busy most of the time anyway, but she truly is my addiction and i want her to know that no matter what im still by her side. That i love her more than she could ever understand. The long term damages may risk so much but i don't care, shes worth it even for the catastrophic end if things go wrong
