Why are there more and more unkind people nowadays?

It's not that people are less kind, but that they choose to protect themselves first.

The cost of doing evil is now too low, and the evil encountered is also increasing,

First and foremost, protecting oneself is the top priority.

I remember reading a news story about an elderly person who fainted on the roadside due to a stroke,

There were many bystanders, but no one helped the elderly person,

A delivery worker saw this and quickly called 120. Later, when the ambulance arrived, the elderly person received delayed treatment, and either passed away or became paralyzed,

Then the family sued the hospital and the delivery worker!

Doesn't it seem like the family has no conscience,

They helped him, yet they want to sue.

Yes, I think so too, so before doing good deeds, protect yourself first.
