It creates unnecessary friction, cultivates anger in the people, and can lead to unfortunate events. When a friend comes to our house, we like him, but on the other side if a funny looking stranger comes to our door we dislike him. This liking or disliking seems to be a natural response but we should not forget that they can bring the feeling of attachment or hatred in our minds. Therefore, even though our expressions may look innocent, we should be careful about them and try to balance them. As such any lie is bad, but when it is done with the malice it is even worst.
Malicious behavior causes nothing, but quarrel and friction.
Not only should we avoid such habits, but we should stay away from those who have such habits. Instead of being vicious, we should be kind to the others. This means to believe in a false faith is a thorn. We know thorn never gives pleasure, but rather they always hurt. In the same way, keeping faith in a false belief will lead us to nothing but sufferings.
