Gambling addiction does not always have a negative impact on gambling addicts, those who are willing to do negative things to get some money have had an attitude that is not commendable long before they are familiar with gambling activities. Gambling addicts have a different attitude, some do disgraceful things in order to get money for gambling and some are professional by being ready to take their own risks without any intention of harming others.
Alcoholics have a harder time controlling themselves when they are drunk, while some gamblers are still conscious of what they have just done.
You might compare a drunk person doing wrong things, and a gambler that is just so into the games that they are deciding to put more and more money in there to "recover" their losses.
It's a similar state really, where you are not thinking straight, and just want the benefit right now. In both cases most of the time you end up in a worse situation the next day after a day of bad decisions.
