Nonsense. It's completely unnecessary. We could be exploring different galaxies by now if not for the petty evils of the earth.
If you could push a button right now that cured AIDS and cancer, all diseases, all crippling disabilities, solved global poverty, put an end to world hunger, eased third world living conditions, stopped all needless suffering, gave everyone basic equal human rights and dignity, would you push it?
I would push it, but after a while we would face the same or other problems.
The circle would repeat.
I think everyone is convinced in some way that evil is neccesary.
- From a state of hunger to fulfillment.
- From illiteracy to litteracy.
- From sickness, to health.
The problem is that we can't define a limit of evil, to what extension is it neccesary?
The spectrum is quite wide as we can see it.
From squashing a mosquito, to starting a nuclear war.
As far as I can see it, there's no limit. If there was, the human will would be severely restricted.
