Millenarianism is a heresy, period. This belief holds that there is a period of Christ's kingdom on earth like some sort of peaceful kingdom.
When Christ returns, it will be the end of the world. That is Catholic teaching.
Remember also, that it is the teaching of the Church that there are and have been many anti-Christ's.
Here is the Pope Emeritus on this point.
As far as the antichrist is concerned, we have seen that in the New Testament he always assumes the lineaments of contemporary history. He cannot be restricted to any single individual. One and the same he wears many masks in each generation. —Dogmatic Theology, Eschatology 9, Johann Auer and Joseph Ratzinger, 1988, p. 199-200
And, here is the CCC on the point of millenarianism.
The Antichrist’s deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatological judgment. The Church has rejected even modified forms of this falsification of the kingdom to come under the name of millenarianism, especially the "intrinsically perverse" political form of a secular messianism. —Catechism of the Catholic Church, 676
Those who seek after such specific knowledge have fallen into the sin of Gnosticism. See other posts on this. There are many sites on line which claim to explain Catholic teaching which are totally in error.
Just remember this-when Christ returns, that is the end of the world and the final judgment. See my other posts on this.

No, the good will be rewarded and the bad punished as natural and supernatural consequences for sins. From Christ's Own words down to the present time, Catholics have held the Final Judgment as part of our basic belief.
