Who told you that the world should be free from suffering?
Do you find any value in suffering?
Do you think it is possible to experience all the beauty and goodness and pleasure the world offers without also experiencing the bad? Isn't good only good because we know what bad is? If there was only good would it really be "good"?
If you where God and could eliminate suffering what would the world look like? Or conversely if there was a loving God what should we expect the world to look like?
If you think about it, a world without world suffering would be nonsensical. Let me put it this way, you can't know light if there never was darkness. In the same manner you couldn't know suffering without happiness.
Now in the real world we do things with little regard to suffering. We hunt and eat animals. We defend our countries, etc. Cognitively we have tools that deludes us from reality, inflating our ego (evolutionary psychology has a lot to say on this). It's just that we make ad hoc and a priori excuses for them.
So I would like there to be a world of less suffering, and this is viably possible to some extent in our world from our time if I am to disregard those with brain deficiencies that cause depression, bipolar, schizophrenia and the such. I see a need for global harmony and anti-nationalism as did Einstein and Nietzsche.
Now if I was god that is a difficult question. Even if a god did exist it would be subjected to the laws of logic. After all god couldn't create a squared triangle, but happiness and suffering are harmonies to logic. So i hope that from this you understand that we are all chained to the laws of mathematics, of nature.
