Like its been said, live feeding carries some risk. That risk can be greatly reduced if it's done right, but not completely eliminated.
Unless you do something bad like leaving the rodent (older then a baby, with teeth and using them) unsupervised with the snake, you usually don't get fatal injuries. But bites and scratches can happen and even if you stand right there, you can't always intervene or do it quick enough.
Some snakes have lost eyes that way.
Then again, many people feed live because it's what works for them. They don't leave rodents with the snake, or they pre kill. If a small injury happens, they treat it. They have done this for a long time and quite successfully.
With live feeding you may have to do a fecal on your snake at some point, esp. if you don't have your own rodent colony.
Both ways have pro's and cons. Both ways can be done right or wrong. Ultimately it has to work for you and it is your decision.
For what it's worth, things like "it's natural" or "the snake needs to hunt and kill for mental stimulation" are not really points you have to worry about. Either method can be successful in raising healthy snakes.
