A Pope is infallible when making an Ex Cathedra statement. "Francis" is not the Pope, Benedict still is.
However, real Popes can error and sin too, they are not God. All Popes are not Canonized. Some are probably in hell.

St. Paul wrote that there will be a revolt first before the antichrist comes (2 Thessalonians 2:3.) We are living through it now.
