Ah, but "necessary evils" are only necessary in human actions, because humans are not all-powerful.
If humans were all powerful medical procedures wouldn't be needed.
And natural laws are indifferent. So if the natural laws come from God then he isn't all-loving, he is indifferent.
If you want to say that God is either not all-powerful or is indifferent to humans then I'd be willing to consider it, but I would challenge how you acquired your knowledge about such a being.
