Evil spirits
Shalom and thank you for your questions! A manifold question requires manifold answers! Regarding Beezelbul, this is not a Jewish concept at all, so this is not in our realm.
In general, the answer to most of your questions is that nothing at all, no entity of any kind at all, comes into existence through any means other than HaShem. One of the most central prayers in Judaism is the Shema prayer. (Deuteronomy 6:4-9) “Hear O Israel the L-rd out G-d, the L-rd is One.” This basic tenet of Judaism teaches us that not only is there no other G-d, but there is nothing else besides G-d. All existence comes into being through G-d.
So why would G-d create evil? Good question. G-d designed a world in which there would be free choice. Our mission is to use that free choice to overcome the forces of evil, paving the way for the time of Moshiach when G-d will reveal Himself, and the world will be entirely rectified. The evil forces will be swept away…and become ‘recycled’ to good.
The book of Tanya by Rabbi Shneur Zalman of Liadi, is a basic text of Chassidic teaching, which includes Kabbalistic concepts. In the Tanya it is explained that G-d created the ‘Sitra Achra’ – Aramaic for ‘other side’ which is the source of evil, in a reluctant manner, like a person who throws something over their shoulder, not wanting to grant it to the recipient face to face. It is ‘a necessary evil’, pun intended. As I said above, it is for the purpose of free choice.
Everything that exists in the realm of good has a counterpart in the realm of evil. Just as there are righteous leaders, there are wicked ones. You can think of this as a muddy pond. It reflects the beautiful trees and flowers around it but the reflection is marred by the murkiness of the water…
According to Kabbala, G-d created the physical world (for the purpose of the ultimate victory of good over evil as mentioned above) through a process of contractions…from spirituality to physicality. In this process, spiritual vessels shattered, and sparks of spirituality became embedded in the physical world. Living according to G-d’s instructions elevates the sparks and redeems them from the forces of impurity – these evil forces are the ‘klipot’ or shells/husks.

Evil spirits have existed but are considered to be a thing of the past, especially in Israel. For a Jew, learning Torah and carrying out its commandments is the best spiritual remedy against negative forces. For a Non-Jew there are the Seven Noahide Laws to provide a spiritual path and strengthening against evil. When we carry out G-d’s commandments, we are connecting with Him, and creating good angels! Deeds which are less than good can create a spiritual atmosphere which is not so good. The remedy is to focus on the good.
The concept of Azazel exists in Judaism in the specific context of the scapegoat that symbolically bore the sins of the people on Yom Kippur, the day of atonement. Firstly it must be emphasized that actions carried out must be accompanied by the correct internal processes. If a person is not attempting to truly change for the better and improve their attitude, symbolic actions will not help. The scapegoat was sent away to the desert as a symbol of acknowledging the existence of evil – but telling it to stay away so that the people could engage in the repentance process undisturbed.
To sum up, there is a principle in Torah (Tractate Avot 4:2) that “(performance of) a mitzvah brings another mitzvah (in its path)” meaning that keeping a commandment of G-d brings about the performance of an additional one. Good energy and good vibrations invite the same. It hs worthwhile exposing ourselves to true G-dly content frim reliable sources, and trying to live our lives accordingly.
