Listen, you worry about this and are right to.
My brother was telling me that while talking to on of those, the special things said that
"people only are nice because somebody is watching. People need to take care for when nobody is watching, because that is when bad things will happen."
Of course that adds on the mindset that you would only do something nice as long as other people can see that you are doing something. It is no wonder that they cannot be bothered to help another human being unless it gets them a like.
