Most people criticize others because it is easy to play the blame game.
Calling someone a fool and criticizing their actions just because it feels good is one of the worst things you can do.
It usually starts with gossiping — speaking behind someone’s back takes no courage. And gossiping feels free of consequences. It is easy to pick up a few mistakes someone made and criticize their decisions.
But if you were put in their shoes, you probably would have done the same thing.
Respect other people’s mistakes with empathy. It is fine to say what you would have done differently. But gossiping will never make you more intelligent.
