No: Not all bacteria are bad; many are important some of the body's most basic processes, including digestion. Bacteria is also a necessary in the formation of certain foods such as cheese.

Help v disease: "good bacteria" are companions on our journey through life, providing necessary elements for our physiology that we can't make for ourselves. Things like vitamins, digestion aids, intestinal balance. "bad bacteria" are similarly constructed microorganisms that cause disease. Some bacteria can be both beneficial and harmful. Go figure, evolution is amazing.

Yes: The difference between "good" and "bad" bacteria is those which are normally with us and don't cause us problems vs those that normally cause us problems. However, no bacteria are ever normally in our bloodstream. As a result, if some of our "good" bacteria from our gut were to enter our bloodstream, we could become septic and very sick.

No: Many bacteria are completely benign, and we would have a great deal of trouble surviving without them. Our body literally is covered with bacteria, inside and out, with some important exceptions such as the bladder and internal organs. The gut is loaded with all sorts of bacteria that actually helps with digestion.
