@ᑕᖇiᗰᔕ-ᑎ Absolutely Human nature can be changed. And it changes in almost every person as he moves from his childhood to a grown person. There are some traits in your personality you change and some that you take through your whole life. And if it should be changed or not, it all depends on what personality we are talking about. Humans have evolved since time immemorial and will constantly continue to evolve. And in that evolution, certain changes take place which are directly or indirectly reflective of changing human nature.
