There are many rare and usual complications for every situation in the hospital....so yes, a baby can die from circumcision just like an adult can die from a routine minor surgery. My job is simply to ask a family if they want the circumcision. I wouldn't be surprised if my hospital performs 100 circumcisions a week. If there is any doubt of an abnormality that could complicate the circumcision, it is not done at immediately post birth. I have assisted a doctor with a circumcision while another was going on next to us. It isn't a blood procedure and can be done fairly quickly. All babies get pain meds.
You may have been one of the unlucky ones to have a botched circumcision...and for that, I understand your viewpoint. But I also know a man who finally went in to get one as an adult and was willing pay for elective surgery (not covered by insurance) because sex was just too painful with his wife. The surgeon came out and said that without a doubt, his insurance would cover the surgery because it turned out to be a medical necessity because of all the adhesions that were attributed to his hyper holy mother being too afraid to touch his male parts as a baby and clean him properly. He has suffered all his life not knowing that what he was feeling wasn't normal. So you can have medical issues from not circumcising.
I let my husband make the decision concerning our son. He picked circumcision. I am glad he did because I do have some concerns related to the kind of hygiene care these men will get when they become dependent on others. I also wonder how well a pre-teen/teen boy actually cleans himself. But again, that is not reason enough for circumcision but it did play into my being just fine with that decision.
However, there are no bloody diapers and the vast majority of babies have no issues. In the US, most boys are circumcised.
