I was intrigued by a question raised. However, I will not specify the details of the question but I will put it in general terms.
"why do we act in assertiveness towards something we know that it's against the morality of humankind?"
with the complexity of our brains. we should be able to make sound decisions and execute actions only after thorough thoughts. again, 'should', I emphasize.
What is the main driver in place when we engage in certain decision-making?
Given a scenario, why do people choose to smoke in the first place when they already know the consequences? it affects their own health, it affects the people around them, it serves no purpose (no, it does not relieve stress. so smokers, do not kid yourselves), it's a waste of money, it stinks, it pollutes (oh dear God the cigarette butts all over) etc.
I would say external factors are so important as to how we react. The people around us, the pressure we take in everyday, the fear we live in, judgements (while most of us only show the world what we want to portray, not exactly who we genuinely are, how convenient is that art yes?)
Have you ever had a major issue with being irrational? Have you ever acted against the principle of moralities?
I am almost certain you have.
Hmmm...let's have some time alone to figure this out.
