what did Michael (archangel) do with catholicism?
His first role is the leader of the Army of God and the leader of heaven's forces in their triumph over the powers of hell.
did he have any struggles or conflicts?
In this role Michael descends at the hour of death, and gives each soul the chance to redeem itself before passing; thus consternating the devil and his minions.

Question: how did he give them a chance to redeem themselves?
