Why is the world cruel?

nobody can get along it's pretty sad

The world isn't cruel but a lot of people are, the world is the world and the conditions for life have not really changed since the pond scum days it's humans that give it the appearance of cruelty because humans drive themselves and others insane and it is traject really .. ~Nemo~

Sin. Death, etc. was brought about when Adam & Eve ate the fruit. Now it's all this.

You probably have heard of 'the survival of the fittest' and 'the food chain' of which man is on the top rung. This is the natural order and necessary for the continuance of life. However, not all things are cruel. Animals are very kind and living to their young and mates and humans are usually so. Many humans are very kind to the young, poor and disabled. You have to look to see these things since it is easy to note the harm/injustices since they are widely publicized and the good news is not.
