I disagree, humans are not all bad guys. I see no reason to conclude that. Bad is a word loaded with theological charge on this forum. A definition similar to all humans have done some mildly harmful thing would be acceptable and demonstrable.
People often are thinking of different things than each other when they use labels
"good" and
"bad".
Our Teacher, the Christ, teaches that our human ideas, individually, of what is
"good" are typically not very deeply thought out and not as far reaching as we think.
One way He teaches this is basically telling us we are all incompetent to judge each other as persons, and barely able even to judge actions (instead of a person themselves), needing work and effort to even do that simpler thing better --
1 “Do not judge, or you too will be judged. 2 For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
3 “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? 4 How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? 5 You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye."
Matthew 7 NIV
(at a certain level of maturity (hopefully not too late in age), Christians begin to realize this applies to us all)
But He says even more about what is
"good" in a more ultimate way -- and not what we think ==
17 As Jesus started on his way, a man ran up to him and fell on his knees before him. “Good teacher,” he asked, “what must I do to inherit eternal life?”
18 “Why do you call me good?” Jesus answered. “No one is good—except God alone. (!)
19 You know the commandments: ‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, you shall not defraud, honor your father and mother.’ ”
Mark 10 NIV
Soon, He would teach them that to simply actively lust after another person not one's spouse is already adultery. He would reproach the religious leaders of that time over and over on their own hypocrisy and on their false accusations and wrong judgments and invented ways to judge with burdensome rules that weren't of God. He would teach that to stay angry at a brother is like murder. We learn that what true
"good" is isn't so effortless or commonplace as we first wanted to think.
It's sort of like the golden rule, even in the pro-active "in everything" form He used --
Matthew 7:12 In everything, then, do to others as you would have them do to you. For this is the essence of the Law and the Prophets.
It's easy! .... Or, well....most of the time.
Until a situation happens, like someone doing a wrong against you, and then suddenly it's not so easy. He teaches us that a more full love is to love even those that have been an enemy (which isn't the same as ignoring their wrong, nor letting it happen over and over, but instead can look like doing good to them even though they did wrong against us).
