To people who think kindness has no value in this world.
"A good person is not kind for the sake of being kind, but because he is happy for being kind.
True happiness is found with others and yourself with others."
It comes to me that some people think that kindness and compassion is worthless, but by saying that you keep this world hostile, you are keeping the negative mindset alive. Though of course it isn't that simple, it would be better if we advocate for what life we want.
Less be the apathetic person, seeing a mugging in the street and shrug because it is worthless to not resist. Apathy is like angel-song to dictators, thieves, tyrants and devils.
