I disagree with this statement. I carelessly do things and people tend to thank me for my kindness and helpfulness, even though I was never intending to do it. People will do the right things without realizing it all the time, in a thousand little ways. I can talk to a friend just to talk, but to my friend, it may have been a sudden, unexpected, and welcome reprieve from a dark and lonely mental space. I can share an otter video because I think otter youtube is great, and in doing so adjust someone else's viewing algorithm away from so much unhealthy/addictive/extremist stuff on that site.
People's actions are rarely with real justice or malice in intention. Most of the time it is nuances of grey, thoughtlessly. Humans don't have the mental capacity that would be required of thinking otherwise.
