Unfortunately, humans are complex animals and this statement does not stand on its own. We all react differently to alcohol, mostly because of physiological differences. The core of the issue is awareness of the reaction and self-control of the consumption.
I want to stress, that this is in no way meant as an excuse for people to act they way they do, I’m just pointing out that your statement is imprecise at best. It is both the kind of person and the amount of alcohol consumed that causes this. On the first part, perhaps you would remember https://en.wikipedia.org/wiki/Two_Wolves for a more nuanced explanation of what exactly is going on.
TL;DR; Some people should drink (a lot) less or not at all and we should all be aware of how we react to alcohol.
