 Lord of the Flies was contrasted with an actual incident from 1965, when a group of schoolboys on a fishing boat from Tonga were marooned on an uninhabited island and considered dead by their relatives. The group not only managed to survive for over 15 months but "had set up a small commune with food garden, hollowed-out tree trunks to store rainwater, a gymnasium with curious weights, a badminton court, chicken pens and a permanent fire, all from handiwork, an old knife blade and much determination". When ship captain Peter Warner found them, they were in good health and spirits. Dutch historian Rutger Bregman, writing about the Tonga event, called Golding's portrayal unrealistic

Lord of the Flies presents a view of humanity unimaginable before the horrors of Nazi Europe, and then plunges into speculations about mankind in the state of nature. Bleak and specific, but universal, fusing rage and grief, Lord of the Flies is both a novel of the 1950s, and for all time.

It really seems like people have too good of a view of mankind.
It also seems like people have too negative of a view of mankind.
Evil can and sometimes does eclipse or enshroud any perceptible goodness in a person.
However, people can be taught how to overcome evil with good.
I'd heard an old pastor quote some other guy saying of the concept of "necessary evil": "Evil becomes regarded as increasingly necessary and less evil"
People have had the attitude of "necessary evil" in regard to just about every perceivable act of depravity, from lying and cheating to sexual immorality and ultimately even murder (although abortion isn't murder, and when else has anyone ever felt justified killing another human being?).  When you take God out of the equation, as people, to varying degrees, tend to do, all bets are off.  And when I say "God", I'm talking about the God that IS DESCRIBED in The Bible.  Regardless of what "people say", The Bible is clear about who God is.  If you're confused about who God is at some point while reading it, there are plenty of people to talk to about different things.  People try to talk about The Holy Bible as if it's two separate writings.  It's not.  The Old Testament is not "The God of Wrath" who is replaced in The New Testament as "The God of Love".  God has always had a high standard and has always had compassion and understanding and has always expected people to trust Him. People today who reject what Yahweh has spoken will suffer the same fate as those who God told to take hold of the Promised Land and refused to do so, instead whining and crying about how evil they think God is. 
People are "basically good", to an extent.  It's not because people are incapable of evil, it's because God has provided instruction on how to live from the beginning when He created Adam.  People have since then taken His instruction and refused to acknowledge the giver OF the instruction, and have tried to tweak His instructions to suit their needs, just like the stereotypical Gordon Gekko - wannabe type who wants a bigger slice of the pie and ends up throwing their business partner under a bus to get it.  Who says there's anything wrong with THAT?!  Who?  Really, WHO?  You?  Why does Mr. BigShot care what YOU think?  Or what your friends and relatives, and/or your neighbor think?  Or his own neighbors and relatives for that matter?  You want something badly enough, whose to stop you from getting it other than your own ineptitude?  God doesn't force people to love Him and act in His ways.  If He did, life would certainly be EASIER for all of humanity...if only we had no free will, sure...
aaaaanyway....
