I think, that the problem is in egoism in everyone of us. We hate things, people, food, feelings, weather, animals, insects We hate everything. We hate because it is easier than love. It s easy to find bad things over the world.
People are lazy to do something for the comfortable life.
We want to have all, everything on the world. But it is not real. So we want to have things, which we could have. We aren t happy from things we have. We want to hate.
