Being corrupt means that you have difficulties differentiating between good and evil not necessarily because you don't understand this concepts, or that you are unaware of the consequences of your actions. But because you're in denial about what you're doing.
Whenever you're suffering from chronic pain what ever the causes of that pain might be, it is going to bring your denial about it.
As the purpose of denial is to keep you functional whenever you are in chronic pain. If there's nothing to do immediately about the pain, then there is no point in paying attention to it or acknowledging it.
So then the pain will bring your denial and your denial will bring your vices.
Not to say that you are not responsible, or that you don't have any agency. But resisting a strong impulses like pain, makes it a lot harder to be consistent in your behavior. The same way it is hard for people that are trying to lose weight to follow a caloric restrictive diet. The longer you have been on the diet the more hungry you get, the less likely to keep staying on that diet. The same with morality the longer you force yourself to have integrity the more intense your pain is going to become for not suiting it with your vices, which is eventually going to cause you to relapse back in to denial and then back in to your vices.
And then there is a vicious cycle of people blaming themselves for using a poor strategy, because they don't understand how their physiology and mind works. Instead of looking at the situation empirically and acknowledging what they know and what they don't, they just conclude that there is something wrong with them.
So then the priority in restoring someone's integrity is to address the underlying chronic pain that creates the Inconsistent behavior. Rather than educate them on morality, or giving them facts, chances are that they are very aware of those.
Whenever you suffer from chronic pain emotional or physical, you are to some degree compromised, you can't hold yourself to the same standards as if you would be well. Because you are always going to fall short from those standards because under present situations it is nearly impossible for you to meet them.
It is better to address your problem sooner than later, because there is such a thing as doing permanent damage. Like if you smoke and you stop soon enough you are going to recover almost completely, however if you smoke for to long and you end up with lung cancer or breathing through a tube in your throat, you can stop smoking but it won't make much difference at that point. There will always be sufferance in the present caused by your past actions, if you stop early enough.
