Well it is meant to be a show of nobility and strength, man versus beast. If it was a fair fight then more matadors would be gored, sadly the bull's are plied with alcohol or drugs to make them drowsey and are often corked as well.
The matador will killl the bull with a sword in most cases, and his assistant will spear a dagger into its brain as a coup de grace. I saw a photo of the daggering on the internet that I was going to tag here but thought better of it, not noble or entertaining by any stretch of the imagination.
