Not showing any concern or kindness towards others.

Uncaring → It is formed from "un-" (meaning not) and "caring" (from the verb "care", which comes from Old English "carian", meaning to be concerned or to feel interest). The word "uncaring" means not showing concern or interest.
Think of 'not' ('un-') showing 'concern' ('caring') — that's why uncaring means lacking concern.
