Resentment can be disturbing and dangerous because you can get to the point of resenting a person and it is so strong that you can even start to have bad thoughts with that person to whom you have resentment, such as wishing them harm.
Totally, it spreads and grow stronger with time. And when it grows to that stage might really go bad or might lead to regret.
It is absolutely right to try to avoid resentment, although it something seem like it is unavoidable. But we should try.
Nice perspective 🤌
