Obviously. Otherwise you'd be trotting out the much more polished responses that trained theologians use to try to explain the all-powerful, all-knowing, all-loving, but unspeakably mean and petty God scenario. Professional theologians and similar shamans have a lot more practice and selling that concept than you do. Clearly:
Man creates fancy cancer causing agent, lets call it ... agent orange. Did God create cancer?
Are you sticking with the all-powerful, all-knowing, all-loving god model? Well, since you're sticking with pure invented fantasy, that's actually a trick question, isn't it? But since that god is involved in every aspect of creation, then: yes. And even if you don't like that answer, there's the fact that despite is apparently boundless mercy and his ability to make otherwise physically impossible things happen (including bringing people back from the dead during publicity stunts), he really doesn't are if pure-as-the-driven-snow innocent infants (and millions of other people) die in agony after months of suffering. Who cares if man is capable of inducing cancer. Are you proposing that ALL such horrible fates, including every way in which a toddler can be made ill and prematurely die in misery is the result of human action? No? I see.
Or put it in another way, "God allows evil, because without a choice, there is no chance to choose"
I see. So, things like childhood bone cancer, or being born with a major heart defect, etc., is just people choosing. OK.
ON the other hand, you being human and being your own god have to answer for the evil you allow to exist. Oh wait, being an atheist, you cannot even say evil exists.
You really are new at this, aren't you? Are you actually saying that the only measuring stick for evil is that which a particular bronze-age desert tribe or two jotted down, and had re-hashed by people centuries later for political reasons? That only people who follow that recipe are allowed to objectively weigh someone's actions as evil? Hint: it's possible to objectively define a value system (which then allows you to separate things into good and evil) without even once having to invoke magical invisible all-powerful but part-time and petty gods. In fact, it's a lot EASIER to define a rational code of ethics/morals if you're NOT using made of fairly tales as the basis for them, philosophically. Why? Because that way you don't have to paint over all of the BS mixed premises, loopholes, and please-don't-look-behind-the-curtain nonsense that comes with basing your value system on imaginary magic.
And don't lie to me saying you don't allow evil, even by your own standards, you allow it. Which makes you pretty hypocritical.
Have you poured your nice strawman a cup of coffee yet this morning? He's probably getting tired.
