selfish

This term carries a strong negative moral judgment, describing a lack of consideration for others that borders on greed or narcissism. It is frequently used in interpersonal conflicts or parental corrections to highlight a failure in empathy or social cooperation.

While it describes a personality trait, it is often used as a situational critique. For instance, a normally generous person can be described as acting selfishly in a specific moment, shifting the focus from a permanent character flaw to a temporary behavioral lapse.
