Many people, feeling far superior to others, spend their time criticizing them and feel satisfied and take pride in doing so. In reality, this is actually a weakness of which they must not be proud.
Every negative word feeds dark entities that use it for carrying out their evil designs.
You might say that people don’t always really think the negative things they say about others.
That may be so, but they nevertheless gave the dark entities the means with which to inflict harm.
Avoid criticism, especially if you are not completely sure about the facts you describe. And even if, for some or other reason, you must speak about the incorrect behaviour of someone, for instructive reasons, try to conclude by mentioning at least one of their good qualities.
Highlighting the faults or the bad behaviour of others has never improved them. Criticism only fuels evil.
