Altruism vs good
“Disturbing emotions not only disturb our own state of mind, they also disturb the minds of others. Self-centredness gives rise to fear and insecurity, which in turn creates distrust. This is why having an altruistic attitude brings a great sense of happiness and peace of mind.” Dalai Lama
I am disagree that altruistic attitude can give us anything good. From a definition of altruism “a person unselfishly concerned for or devoted to the welfare of others”. “welfare of others” is where altruism becomes a problem. Most of us have different view on what is “welfare” is. To make it worse we cannot predict a long term effects of our actions and not good at predicting side effects.
Another side is a responsibility for our action. When your action directed solely to others it is they who have to deal with consequences. Therefore you lost direct feedback of you actions.
