Why isn’t it better to place us in Heaven from the outset? What is the point of a world with sins and choice and repair?

Why? Because just as you need to work to earn a salary and nobody is going to support you, so too you need to keep commandments in order to advance your standing in this world for the sake of the World to Come.

God is good because you do not have to pay Him for being alive.

I don’t know. It would be worth asking Him.
The question of evil is an objection, and therefore it requires resolution. Here you are asking a question, not raising an objection, and therefore the absence of an answer is not significant. There are many things I do not know or understand. So what?

The World to Come or Heaven (let’s call it that) is the place where the Tree of Life and the Tree of Knowledge were. Because of the sin of the first man and his wife, we were removed from there, and therefore it is not precise to ask why we were not placed in those places from the outset.

Moshe — the fact that “you need” to do this, you concluded simply because that is the existing situation. I am saying from the outset that this situation is not the ideal one. Don’t you think it would be better from the outset to give reward without work? Who decided that one has to work? After all, any reason you give me will be canceled out, because I can simply say that the Holy One, blessed be He, could have eliminated that reason.

Rabbi — this question is part of the problem of evil. The suffering that exists in this world is an evil thing. You explain that it exists because a world with commandments cannot exist without suffering. So I am asking why there need to be commandments in the first place at all (and you answer, “I don’t know”). From here it follows that your whole answer is simply based on accepting the existing situation (I doubt you have some intuition telling you that a world with sins and commandments has to be created before rewarding those who dwell in it. At least I do not have such an intuition). From here it follows that to the problem of evil itself you also need to answer, “I don’t know.”

Moshe, regarding your second response: why did He place the Tree of Knowledge and the serpent there in the first place? Why did He create Adam and Eve so gullible? He was not surprised by the sin, right?

I don’t know whether you read what I wrote, because from what you say it seems you didn’t.
Every answer is based on assumptions. Moreover, with respect to the Holy One, blessed be He, the assumption is that we do not understand everything He does. Therefore, when there are questions, that is not disturbing; only objections require an answer. About evil, this is an objection, but about the need for commandments, this is a question. I also have no idea why He created the world at all, even if it were a perfect world. Why not ask about that too?
There is no point in grinding water and asking questions that nobody can answer. Only if there are objections does it require thought, because objections may refute the entire theory (= faith).
In short, my answer turns an objection into a question.
