Would it not be more appropriate if, instead of God himself (in the form of Jesus Christ) fighting Satan, he would leave this to humanity?

Answer: Every Christian is called to fight against the power of Satan. However, every Christian knows that he can win this battle, at the end of the day, only with God’s strength. This strength from God is given to each Christian, through Jesus Christ, who acknowledges the true God from true God and who also believes that for us and for our salvation, He came down from Heaven. By the power of the Holy Spirit He was born of the Virgin Mary and became man (the Nicene Creed). A Christian receives the strength to fight Satan’s power through the devout listening to the Word of God and by receiving the sacraments. In this way, the resurrected Lord is effective and powerful in the faithful by the power of the Holy Spirit.
