>>Nature by default doesn't have nuclear weapons....

While I agree with your sentiment, just would like to point this out that nature does have nuclear weapons, pretty scary ones for that matter: the stars.

Also, if we take these things to their logical conclusion, then the nuclear weapons created by human beings are, of course, created by nature - in this case, indirectly, using the humans.

This is just to point out the logical aspects of the arguments. Other than that, I do agree with you that we, the humans, need morals to sustain a better life for most human beings.

These are nuclear, but not weapons. Nature doesn't have an enemy.

>>Nature doesn't have an enemy.

How are you so sure? Have you talked with Nature by any chance? Has Nature given you this statement, say, in English? I am not trying to be sarcastic here, I am dead serious.

I for example, think that Nature likes to fight many of its creatures against each other. e.g. polio viruses against human beings

I may be wrong, but one cannot be so sure.

" Nature likes to fight many of its creatures against each other

Anthropomorphising can only go that far. Do you know any physical law that has volition?
