Answer 1

"Perfect use" means that people are using a condom consistently and correctly.  This definition still leaves room for the possibility of the condom itself failing (breaking).  Condom breakage = no protection.

Condoms break, even when used "perfectly." It's just a fact of life.  

Answer 2

YES, THATS A FACT TO BE CONDONED.

Answer 3

holes, slips off, people lie, It breaks, it goes flacid leaks from the base. Another guy lol, tons of reasons. In the old days  it was funny or a kids prank to go in to drug stores and pin prick condoms that was before aids though. how much sperm it takes to make someone pregnant is not known for example. If you had a little on your finger and you put it up there. If two individuals were super fertile it's a possibilty however remote.
