这个规矩的真实原因其实是因为如果杀了人的话，不管早晚，白人就会骑着大象，带着猎枪杀来；成百上千的棕种人也会敲着锣、扛着火箭弹、举着火把赶来。那时，丛林里的生灵就遭了殃。兽类为自己立下这样的规约也是因为人类是所有生灵中最弱、最没有防御心的族群，袭击人类一点儿都不光明正大。（The truth about the rule is: if you kill a person, the white will rush by elephants to you with shotguns, no matter it is early morning or late night; while thousands of the brown will come with gong sounds, torches as well as rockets on their shoulders. Now the creatures in the jungle will suffer. The beasts make these rules partially because attacking human is not fair play, since this species is the weakest and less defensive at danger.）
