The world of men is full of deception and trickery. Trying to ensnare others and gain the upper hand, each seeking their own advantage. Religion, government and individuals do this.
Of course so does the whole animal kingdom, of which we are a part. Using camouflage, webs, poison, disguise and sheer strength, each creature seeks to kill and often eat anything weaker than itself. It's called the law of the jungle.
Not a pretty picture. Getting angry at the god that created all this violent and selfish world would be justified but I won't for two reasons.
1) No such god exists.
2) The world with all its faults, works well for me and I do so enjoy a rare steak.
