the.com/indignation

means A sharp, righteous anger stirred by something that feels unfair or unworthy of respect.

from From Latin indignari, 'to regard as unworthy' — built from in- ('not') and dignus ('worthy,' the same root that gives us 'dignity'). So at its core, indignation is the feeling of watching something treated as if it deserved less respect than it does, or someone acting with less honor than they should.
