The total amount of suffering per year in our world is beyond all decent contemplation.
During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. About 20,000 African children are dying from starvation and disease every day.
In a universe full of radiation, electrons and selfish genes, some people are going to get hurt, other people are going to get lucky, and you won't find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.
Seriously, when are humans gonna realize that they are just animals? We think we are above animals, we think we are different than them but the fact is we evolved from the same primordial soup as them.
The truth is we're just animals who became smart due to our larger brain size.
