Cruelty is a tyrant always attended by fear.

The proverb presents cruelty as a form of domination inseparable from fear. Its image of a tyrant makes fear part of how cruel power operates, not a chance consequence of it.

It condemns rule through harm or intimidation. The saying does not specify whose fear accompanies the tyrant; its central point is that cruelty cannot stand apart from dread.

Use it to criticize someone who tries to control others through harsh treatment or intimidation, or to reflect on the fearful atmosphere such conduct creates. It suits a serious judgment rather than lighthearted advice.
