Selfishness is a sin, but it does not carry any criminal responsibility; excessive selfishness is not guilty, but it violates morality.
Selfishness can exist, but it cannot lead to ruthlessness and indifference.
Lao Tzu said: "You are born as a human being, you cultivate yourself, you help others, you are like water, you live in the abyss of evil and do good, there is no exception."
Do one good deed every day and accumulate good deeds.
We should all be kind.
Intention: Do one good deed every day, and make one mistake every day.
