I wouldn´t delimit humans in good or bad/evil.

Take a sociological experiment. A person is put to apply electric shocks to an another one, as punishment. Of course, in reality the other one does not get shocks, but through sounds, imitates being electrocuted. It was shown that, while having pressure on from others to increase the voltage, a person is capable to induce a voltage to an another which would fry the latter. This means killing, under pressure and knowing that what one does is just, correct. Is this person, who applies electric shocks good or bad?

Therefore I would rather delimit humans in loving or scared. If loving, no love can exist without self-love, because, at a higher level, love is supposed to be universal, a state of being. If one does not love him/herself, he/she tries to grasp love from outside. But we know 

that parents die, loves end, sometimes are mere illusions. (Just to take a dudu...). 

If we would not love ourselves, how we would survive losts? Apostle Paul said, we are empty without love. Scared humans are those who do not love. When we are scared, we classify, we judge and we victimize. Good, bad... Pope John Paul forgived the man who attented on his life. He loved. He did not judged. He forgived. He forgived the agressor probably considering that the agressor did not know what he was doing ("forgive them because they do not know what they´re doing"). There are not many persons like this, regardless of their religion. Yet, there are. These people, in a way or another teach love... So, in my opinions, we dwell into harmful and useful acts, which results might be good or bad, but we are merely, in a way to speak, unconscious beings. If we dig up a childhood, we see that we are, in a cognitivist way of saying, programmed. Then we deprogram (or not) ourselves, make or adopt other programs. The bare - and maybe sad truth is, that our mind is in a way computer-like, filled with programs, and thoughts. We think. We think all the time, emit opinions and grow in importance. Then we realize we might be mistaken and change opinion, but with the same conviction. We cherish our convictions, because they relfect our values, love for good, for truth, for correct judgement, etc., etc. We apply our convinctions on ideas, even if, through the years we sometimes end up sustaining opposite beliefs. We keep busy all the time. But there are people who transcend good or bad through love, forgiveness and gratitude. I think humans are marvellous, creators of thoughts and dreams and, at an ultimate level, able to transcend values through love. This is the royal crown of humans. Last, but not least, love develops pleasant feelings through neurotrnsmitters, which stimulate brain functions. Why are we fighting between good or bad? I guess not becase we have limited life. Animals have it, too, yet they fight for survive, not for immortality and they accept and know their death. I think we ramble between good and bad, being neither, because we have to survive, tend to write history, our own, the humankind´s´, the planet´s, even the universe´s if possible. If we fail in our lives even, we feel miserable. It is the trap of mind and knowledge. We want to know everything and through knowledge, rule. Maybe this will change humankind. And maybe in a "good" way. I was not scientific on this, I hope I was with common-sense though. Rambling ideas preceed science. BTW, nowadays it has been shown that even water mollecules modify their structure depending on emotions, words that are addressed to - and love and gratitude create crystal-like regular shapes in water molecules.

So the question I would put is: Humans - are they loving or frightened beings?

cheers!
