In my opinion, it is important that we be careful of anyone and do not immediately trust others. We can also do research before taking action. Insight and science are also very important so that we are not exposed to deception and harm.
in fact in this world we may trust everyone, but believe that it is not entirely straightforward to believe. because everyone can stab us in the back. because sometimes they also have envy for us. so we really need to be more careful.
