This one is almost always used incompletely to reinforce the idea of power over kindness.
"It is better to be feared than loved, if you cannot be both."
When you leave off the second part it loses the message that’s it’s best to be both.
@Mort Even without finishing the quote, I always tell people they should add "as long as you can stay the most powerful", because if you stumble & lose the fear - your dead. If they love you & you stumble, they do everything they can to help you back up...
