Tolerance is a virtue, which is what we often say. However, we should not be tolerant at all times. Limited tolerance can reflect a person's demeanor, and unlimited tolerance will be said to be foolish. People should have their own principles at all times, tolerate people and things that should be tolerated, and never tolerate those that should not be tolerated. If you don't help evil, you can't look at or help people who are evil, and you don't do things that harm others yourself. Sometimes, tolerance and not helping evil are contradictory. Not all evil deeds are out of evil thoughts, but some are forced. Even if such behavior causes trouble to others, it is understandable and tolerance is natural. If human nature is evil, it really needs careful consideration. It is best to nip it in the cradle, and don't wait until the injury is caused to regret it. It can be said that tolerance for the wicked is like cruelty to oneself, that is, helping evil. Not helping evil does not mean never forgiving, and proper understanding is also in line with human nature.
