The statement is true. Fulfilling simple requests of an individual who is angry or violent may reinforce their behavior and give them the impression that they are in control of the situation. This can escalate the situation further and may lead to more aggressive or violent behavior. It is important to maintain control of the situation and not give in to unreasonable demands. Instead, it is best to remain calm, assertive, and communicate clearly to de-escalate the situation and seek help from trained professionals if necessary.
