Do good people in life have good rewards?

Having experienced a lot of things, I have really realized that being a good person does not necessarily have good rewards.

I remember thinking that I also took the initiative to do a lot of good things, things that were beneficial to others. But in exchange for what! Just ask others for a little thing, and no one will do it for you. Since then I've started to re-examine everything, maybe a lot of people don't deserve your help and be nice to him, for them what you do is what you should do.

Watching some videos to this day has made me even more complicated by a lot of human nature. One video is about a 44-year-old man who rescued a car that fell into the river, a total of 19 people. However, in the process of saving people, he was infected by water in his lungs. After spending all his savings, he died without money for medical treatment, and none of the 19 people he saved came to visit. Maybe these people are afraid to find their own money to see a doctor. Then you don't have to think about how your life may be gone without others. I was really shocked to see this video, how can human nature be like this, and what is the difference between these people and animals.

Perhaps, there is always a good side and a bad side of human nature, and this may be the bad side of the soul. And we kind people will be more cautious in doing things in the future, and don't let our conscience feed the dog.
