God need satan..we need satan?

I would like especially Catholics to discuss this:

God need satan…we need satan…
God gave us the ability to choose, God presents one arguement and satan the other…it is still our choice to decide which course of action to pursue…

Evil tends to be selfish,
Good tends to others…

Any comments you can give would be greatly appreciated.

*The Creator is not dependent on the creation. All things exist because they have a purpose. If there was no purpose for Satan to exist he would not exist. Satans purpose though is dependent on God who is Purpose itself.

God needs nothing.
Satan needs God.
We need God.*

God doesn’t need Satan. Lucifer had free will and chose himself over his Creator.
We don’t need Satan. Evil exists in our fallen world because of Satan’s temptings to join him in his choice of self over God. We need God, not Satan.

Perhaps you can expound on your intention of the word “need”, because you may mean something that I did not address.

God doesn’t “present an argument”. God presents Himself. He provided revelation of Himself to us. It could be said that Satan certainly presents arguments against God, however.

The rest of your comments are essentially correct.

NATURAL IMPULSE
THE good impulse (yetser tov) and the evil impulse (yetser ra) are pictured in Jewish literature as wrestling in perpetual conflict within the heart of man. Satan is usually identified with the yetser ha-ra, the evil impulse. In the book of Job, Satan’s function is described as that of testing the sincerity of men’s characters. In Talmudic literature, Satan’s function is to strengthen man’s moral sense by leading him into temptation. It has been said that every man living shall assuredly meet with an hour of temptation, a certain critical hour, which shall more especially try his mettle.

According to a midrashic statement (Genesis Rabbah 9:9), the existence of the yetser ha-ra in the heart of man and the struggle to overcome it lends high value to the good that emerges from the inner battle. The two conflicting impulses, the good and bad tendencies, are said to be implanted in man as a consequence of his having been formed from the dust and endowed with a soul (Genesis 2:7).

According to rabbinic thinking, the evil impulse is to be found in man at birth; the good impulse begins to develop when he is thirteen years old. The teachings of the Torah are referred to as the antidote to the yetser ha-ra. Similarly, Ben Sira (21:11) states: “The man who keeps the Law controls his natural tendency.”

In commenting on the two yods in the word " ", (Genesis 2:7), the rabbis declare that God created both the yetser tov and the yetser ra (Berakhoth 61a). The command to love God “with all your heart” they interpret to mean “with both your impulses” (Berakhoth Ma), since both human elements can be employed in the service of God. “Were it not for the yetser ha-ra, no man would build a home or get married or follow an occupation” (Genesis Rabbah 9:9). The phrase “very good” (Genesis 1:31) is therefore explained, as alluding to the yetser ha-ra, frequently used in the sense of the productive urge.

Genesis 1:31
And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, a sixth day.
