Q: If the Creator exists, He must be looking over everyone with eternal love. Why, then, are there so many who are punished?
A: Your question only indicates the place you’re in, because we can only draw conclusions from our own degree of development. If we rise spiritually, everything will change for us: our conclusions, our opinions and even the way we see the world. We will see the world as something good, perfect.
However, in your current situation, you can only see a fraction of reality, where it is very hard for you to justify and understand the Creator. I know that from my own experience.
Let’s wait until the Creator is revealed to you, and then you will be able to justify Him. He who justifies the Creator is called “righteous.” One must become a complete righteous to discover the Creator and His actions and know everything about Him, in order to justify Him.
For that, we must be identical to the Creator because we can only know if we become like Him, out of equivalence of form. I suggest you read Baal HaSulam’s Introduction to The Study of the Ten Sefirot.
