Doing virtue.

When I watch people who try to do virtue to help disasters on TV, I often think is it really useful for the victims ?
I have heard the saying from one of my friends who suffered such a disaster.
He said he received some kindness which was unnecessary for him from strangers.
However, he was not able to say that.
In my opinion, no one blames the people who are doing good things.
The worst thing is a person who believes that they are doing good things without doubt.
It is just gratification of the ego.
I think you always need to reflect about yourself all the time.
Doing good things is not always perfect.
You need to imagine what they want.
It's difficult doing good for others.
