not true. papal infallibility applies only to proclamations of official church doctrine, not of his deeds or opinions. and sometimes opinions relating to doctrine do get rejected, even if it comes from a pope. quoting from wiki:

"In July 2005 Pope Benedict XVI stated during an impromptu address to priests in Aosta that: "The Pope is not an oracle; he is infallible in very rare situations, as we know". His predecessor Pope John XXIII once remarked: "I am only infallible if I speak infallibly but I shall never do that, so I am not infallible". A doctrine proposed by a pope as his own opinion, not solemnly proclaimed as a doctrine of the Church, may be rejected as false, even if it is on a matter of faith and morals, and even more any view he expresses on other matters. A well-known example of a personal opinion on a matter of faith and morals that was taught by a pope but rejected by the Church is the view that Pope John XXII expressed on when the dead can reach the beatific vision."

and i don't believe in that. my soul can burn in hell
