Which term describes something that causes pain or suffering?

The term that describes something that causes pain or suffering is "harmful." This term specifically conveys an aspect of negativity, suggesting an experience or substance that has detrimental effects, leading to distress or injury. In contrast, options such as "beneficial," "neutral," and "advantageous" all imply positive outcomes or a lack of negative impact. For instance, while "beneficial" refers to something that brings positive effects, "neutral" indicates a lack of any notable effect, and "advantageous" suggests that something provides an advantage or benefit. Therefore, "harmful" is the only term that encapsulates the idea of inflicting pain or suffering effectively.
