Answer:
One of ways Golding shows conflict between savagery and civilisation is when Jack and some of the other boys are killing the first pig. Jack chants “kill the pig, cut her throat, spill the blood”. This suggests savagery as the boys are being violent and aggressive when killing the pig and they don't care about it.
By keeping the natural human desire for power and violence to a minimum, civilization forces people to act responsibly and rationally, as boys like Piggy and Ralph do in Lord in the Flies. Savagery arises when civilization stops suppressing the beast: it's the beast unleashed.
