That is not St. Michael's role.  

From a soul in Purgatory;
What is the best way of honoring St. Michael?
The best and most efficacious way of glorifying him in Heaven and honoring him on earth is to spread devotion to the souls in Purgatory, and to make known the great mission he fulfills towards these suffering souls. It is he who is entrusted by God to lead the souls to the place of expiation and to bring them to their eternal home after purification. Each time a soul arrives to increase the number of the elect, God is glorified, and this glory in some way communicates itself also to the celestial minister. It is an honor for him to present to Our Lord the souls that will sing their thanks and His mercies through all eternity. I could never make you understand the intense love which the Heavenly Archangel has for his Divine Master, and the love which God in His turn has for St. Michael. Neither can I convey to you a true idea of the love and pity St. Michael has for us. He encourages us in our sufferings by speaking to us of Heaven.

 How do they celebrate the feast of St. Michael in Purgatory?
On that day St. Michael comes to Purgatory and returns to Heaven with a great number of souls, especially with those who had been devout to him in life.

The exorcist was Father Miguel Pedroso. His calm and calm gaze, his words of deep and gentle sonority, his unshakeable courage and faith, his fight against the devil … everything in that priest was exorcistic.
There were huge lines to receive the blessing of this priest at the end of the Mass. The blessing was received on the knees, in the “murmur” that separates the altar, as if to communion. The priest, very calmly, passed from one to the other, blessing, giving advice, smiling and exorcising … His face conveyed tranquility, faith, strength and meekness, together with an unspeakable happiness. Many who came from afar to converse with him returned in amazement at their tranquility of those who are at peace with God. Needless to say, the demon hated this priest. And, from the high altar, St. Michael the Archangel stood before everything.
Who was this priest? What parish is this? What image of São Miguel do I speak?

São Paulo was growing a lot and it was necessary to widen streets, build buildings, modernize the city. In this context, the chapel of St. Michael the Archangel was expropriated: great sadness among the relatives.
But the Catholic faith is strong in the Alian family. In 1938, Miguel’s heirs built another chapel, thus transferring the image of San Miguel Arcanjo to the neighborhood of Mooca. It is there until today.
Although a priest sometimes came to pray Mass and to assist the faithful in the Chapel of St. Michael the Archangel, she did not have a permanent priest. So, to the greater glory of God, the Alian family decided to donate it to the Metropolitan Curia, which finally transformed it into a parish.
On April 21, 1960, the new parish had its first Mass and the first parish priest, who remained there for many years, loved by all the faithful of the region: Father Miguel Pedroso; the exorcist priest.

The pregnant woman and the devil’s hand
There is a fact that has marked me for life. This fact, which impressed me greatly, was when Father Miguel Pedroso took the demon’s hand from a pregnant woman. I have never forgotten this case, which was narrated in the following account:
The devil’s hand on a pregnant woman about to give birth

I then saw two ladies tidying up the church and I went to talk to one of them, who invited me to watch the "little word" that Father Miguel was addressing to a group of young people in a house next to the church. I still got the end of the conversation, which I summarize.

The priest said:

I was in my parish when people came to me to exorcise a pregnant woman who was in the hospital and scared even the doctors. Immediately I got ready and went with the family to the place.

On the way, they told me that she had attended a spiritist center, and after that had never had any rest: family quarrels, mismatches with her children, her husband had lost his job ...

Apparition of St. Michael
It is evident from Holy Scripture that God is pleased to make frequent use of the ministry of the heavenly spirits in the dispensations of His providence in this world. The Angels are all pure spirits; by a property of their nature they are immortal, as is every spirit. They have the power of moving or conveying themselves at will from place to place, and such is their activity that it is not easy for us to conceive of it. Among the holy Archangels, Saints Michael, Gabriel and Raphael are particularly distinguished in the Scriptures. Saint Michael, whose name means Who is like unto God?, is the prince of the faithful Angels who opposed Lucifer and his followers in their revolt against God. Since the devil is the sworn enemy of God’s holy Church, Saint Michael is given to it by God as its special protector against the demon’s assaults and stratagems.Various apparitions of this powerful Angel have proved the protection of Saint Michael over the Church. We may mention his apparition in Rome, where Saint Gregory the Great saw him in the air sheathing his sword, to signal the cessation of a pestilence and the appeasement of God’s wrath. Another apparition to Saint Ausbert, bishop of Avranches in France, led to the construction of Mont-Saint-Michel in the sea, a famous pilgrimage site. May 8^th, however, is destined to recall another no less marvelous apparition, occurring near Monte Gargano in the Kingdom of Naples.
In the year 492 a man named Gargan was pasturing his large herds in the countryside. One day a bull fled to the mountain, where it could not be found. When its refuge in a cave was discovered, an arrow was shot into the cave, but the arrow returned to wound the one who had sent it. Faced with this mysterious occurrence, the persons concerned decided to consult the bishop of the region. He ordered three days of fasting and prayers. After three days, the Archangel Michael appeared to the bishop and declared that the cavern where the bull had taken refuge was under his protection, and that God wanted it to be consecrated under his name and in honor of all the Holy Angels.
Accompanied by his clergy and people, the pontiff went to that cavern, which he found already disposed in the form of a church. The divine mysteries were celebrated there, and there arose in this same place a magnificent temple where the divine Power has wrought great miracles. To thank God’s adorable goodness for the protection of the holy Archangel, the effect of His merciful Providence, this feast day was instituted by the Church in his honor.
It is said of this special guardian and protector of the Church that, during the final persecution of Antichrist, he will powerfully defend it: “At that time shall Michael rise up, the great prince who protects the children of thy people.”
