You help others, but they turn around and develop resentment towards you. There is a very common psychological mechanism behind this called the Malicious Helper Effect. It's not that the other person is ungrateful; rather, this resentment is sometimes subtle and uncontrollable. Each of us has an innate need to maintain narcissism, pursue equality, and feel a sense of superiority. When your help and support breach the other person's sense of security, their self-esteem and self-identity can be threatened, even leading to damage in their self-evaluation. When the other person cannot cope with their own vulnerabilities, incompetence, and other negative emotions, they may project anger onto you, developing feelings of dislike and resentment. If they also carry unresolved trauma, they might even distort their perception, doubting your true intentions and motives. To avoid the Malicious Helper Effect, the best approach is not to offer unconditional, selfless help indiscriminately, and not to proactively do things you believe are beneficial to the other person before they even ask for help. We must learn to help appropriately, never interfere excessively in others' lives, and avoid taking on their personal issues.
