Why do people think that fools and garbage people deserve to die?

Probably because of fear of being damaged or influenced by people with mental and intellectual problems.

Of course, not all people think so.

Many people may be more responsible and compassionate. Willing to help such people appropriately and correctly.

Especially for those who do no harm to others, we should care more!

Even people with abnormal emotions should be persuaded and guided. Including consulting a psychologist. Urge family members to take care of themselves, etc.
