They are certainly in a great deal of pain and trouble while they are addicted. But if they can recover (a big if for a lot of people), they are better (wiser) than ever.
Overcoming addiction is a greater and greater challenge for humanity because, for the most part, civilization has gone bat-guano crazy. Why be sober when the sober world is nuts?
I have known a lot of addicts. The big question for them is always, will life be any better if I am clean and sober. In 2023, the answer isn't exactly clear.
What I mean is you are not dealing with a human being when they are in their addiction, using/drinking. Can’t trust them at all. They don’t see you as a human being.
I got sober off the booze 33 years ago. My worst day sober has always been a thousand time better than my best day drunk.
