Sinful people should always be distant and never make them their friends. Karna was such a great donor, but being with Duryodhana, he also became a part of his sin and in the end he died in battle.
If you live with a person who is selfish, then no one will respect you. Even such people are considered insignificant. Duoardhan was one of such unarmed humans and he eventually got the death penalty.
Everyone should always keep a distance from humans. Such people not only get respect for society, but they are seen with hatred in the house. Such people can also harm you.
According to Vidur, those who do evil or do the work of putting a foot between two people should stay away from such people. Such a person not only becomes a partaker of sin, but also makes you a partner.
People who give misery to others can never be happy. Therefore, by living with such people, you change your happiness into misery. The fate of such people is also not supported, so it is in your goodness to keep away from those who give pain to people.
