If you publish something, you by definition intend people you do not know, the wider public, to read it (if you really wanted to share your thought with that one person, publishing is not required).

Choosing to do something that affects someone else while being unaffected by how they react is not normal and indicates sociopathy.

People paying attention to how they affect others, how others react, and changing as a result of their feedback is basically how society exists. Most people are wired for this. People who are not wired for this… There is nothing stopping them from hurting someone for personal benefit, for example.
