Hi, laurelin.
I feel that you will never get an answer to that unless you approach it from another angle. First we need to consider what sin (or evil) is and how it comes about, and then we can go on to that.
You probably remember James 1:14, 15: "But each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin; in turn, sin, when it has been accomplished, brings forth death." You will note that simply having a desire is not in itself sin. It is only unbridled desire that is acted upon that creates sin.
Viewed in this way, then, it would be fair to say that it is within the power of anyone or anything possessing free moral agency, to create sin and/or evil. Just as we are not born doctors or philanthropists, so we are not born liars, rapists, or killers. We have to make decisions to become those things.
Some will say that I am begging the question here, but I'm not. Yes, Jehovah created us with the capacity to create evil, which according to them, makes him culpable for the evil that we create. However, consider a few things:
If you robbed a bank and when on trial, you used the defense that it is all your parents fault, because if it wasn't for them you wouldn't be there to commit the crime, do you think the jury would buy it?
Or, say that you make tools or exquisite vases. They have the capacity to kill other people should their owners decide to use them in a wrong manner. Would the owner's malfeasance make you blood guilty?
Yes, some say, but Jehovah should have created us without that capacity. In other words, what good is free moral agency? It's caused all these problems, so shouldn't it be done away with? Well, put yourself in Jehovah's place. If you wanted a companion, would you want a robot, or someone like yourself, capable of thinking and reasoning --- and disagreeing at times?
Or, if you wanted a life's companion, would you rather have a vibrator (or blow-up doll), or would you rather have a real live human in spite of the fact that they might have headaches (or fail to shave often enough)? I don't know about you, but I find that choice extremely easy to make. Is it harder? Sure. But the rewards are a million times greater.
This subject is closely related to the way that many roundly condemn Jehovah for condemning millions of people to death. What they don't consider is again, how? Is he going to hire a batch of mercenaries to go in and merrily blow everyone away? Or could it be that he is merely honoring their demand as free agents to take his old rule book and shove it? One glance at the world today and it is glaringly apparent that we humans don't have the foggiest idea of how to run our own lives, and are running everything straight into the ground with horrendous consequences. But at the same time, we sure as hell aren't about to listen to him! (And don't get him and his desires mixed up with the teachings and desires of the religious leaders --- of any kind. Jehovah himself roundly condemns them as phonies.)
In my book, those who condemn Jehovah on this basis are barking up a wrong tree, and merely demonstrate one more facit of modern society's penchant for declaring themselves victims --- and then milking it for all it's worth.
I have no respect for that.
