@Alan McDougall,
An alternative perspective:
Here is a question - what would the world be like if there were NO suffering, 'evil', or anything of the kind? I mean it is crowded enough as it is, isn't it? Be tough if we had to share the place with all the species that have become extinct (i.e. about 99.9% of species) or all the beings that have died (i.e. about 99.99999999% of beings).
Or would you say, let's just reduce suffering by X%? If so, what percentage? What if there were only 10% of all the suffering in the world left? There would still be suffering? What if a smaller percentage died, or got sick, or became extinct? Would it be any better?
Is there, or could there be, a world where there is no suffering, nobody goes without, nobody dies or gets sick? It sounds very much like the traditional depiction of another realm to me. Nothing like 'the world' that we know.
I don't think it is conceivable to have material existence, the kind of existence that we find ourselves in, without evil and suffering of various kinds. It is up to human beings to try and ameliorate it as best as possible, through medicine and political means, and the like. And objectively, medicine has done an enormous amount to relieve suffering over the millenia.
But at the end of it all, if you are a material existent of any kind, then it is inevitable that you will die, loose things, get into accidents, be subject to illness, and so on. it will probably also be inevitable that there are calamities such as natural disasters, and so on. How could it be any different?
The question I think that could be asked is (and this may sound corny, but) 'why are we here'? In the old traditions, there is a view that the world is only one among various realms of existence and our being here is not accidental. Hence 'this realm' as one among others, and one in which suffering is an inevitable part. Hence the ancient idea, Eastern and Western, of 'the world' as 'vale of tears', and so forth, from which the righteous are released according to the various soteriological doctrines of the different faiths. The World, in these doctrines, is not wholly evil, nor entirely good, but humans can discern the two, and hopefully realise the unalloyed good which, as humans, we alone are able to discern.
