It appears to me that not all anger is negative. Can’t people find concentration, find energy in their anger, and achieve justice?
Indeed, having anger can serve as a driving force for doing good. However, we must distinguish between anger that stays within healthy bounds (i.e., does not incapacitate us and is not excessive) and anger that escalates into resentment (a sustained and intense form of anger that can cause exhaustion, division, and even medical issues). If we fail to recognize this difference, we risk becoming resentful and believing that it is ultimately beneficial rather than harmful.
