Hi @vieira,
I like what Cranstron said, "you always have to try to find humanity in a man", I always like to hear statements that remind of positive views. I agree with you, Cranstron and @awkedev that circumstances and culture play a huge part in person's ethics and the eventual breaking of those ethics.
"A person may be acting in a way that he considers morally correct, while others think his attitude is deplorable." - In the article, I was referring to acting in a way that that the person considers morally correct, but I failed to explain that very well.
"You said that people should always think about the cost / benefit, I think that is the attitude that all people have always, in another publication of yours we were talking about exactly how people seek their own benefit without true altruism." - One of the topics that interest me a lot is how to make a balance between personal gains and altruism. I think we all want and need both. But the philosophy behind these needs and their balance tickles my mind.
Thanks a lot for the thoughtful comment, I'm very glad I've already found Steemians who find my thoughts engaging and make an effort to improve and expand them.
Cheers!
