In a private message, this guy says he can never control his hands and always fails to adhere to trading discipline. What should he do?

After losing everything, just exit the circle; learn and understand before you lose everything. There isn't really any other way; most people are in the former category, while only a few can walk the latter path. If you realize you belong to the former category, it’s better to exit early while you still have some capital left.

Adults should take responsibility for their actions. If you are not responsible with money, aren’t you just gambling? You know that this way you will lose money, yet you cannot help but do it, which means you are already blinded by gambling and have lost your rationality. Think about whether you are in the former or latter category. Discipline is meant to protect you, not to restrict you.

The market's law of survival of the fittest is cruel; bulls earn the bears' money, and bears earn the bulls' money. Contracts are a zero-sum game, and leverage is the devil's gift. Being able to control your hands and follow trading discipline is just the first hurdle; after passing this hurdle, there are still 81 difficulties ahead.

If you get stuck at the first hurdle, take a moment to think it over; coming to terms with this early is beneficial for you. The market does not have an obligation to ensure everyone goes home with a full load.
