OP, do you understand the (very reasonable) challenges being raised to your patient management, and questions about your training and certification? "Just because fire already started", and "I got confused with old protocols", and "it can't hurt the patient" are NOT valid ways of thinking about patient care, and reverse decades of evidence-based medicine (research), undermine the professionalism of our industry as a whole, and amount to poor patient care (which ultimately is why we all do this...). Do you see where these (wise) people are coming from?
If you don't follow protocol (or loosely defined best practices) in cardiac arrest, which is relatively black and white, what indications would your supervisors (or QI staff) have that you follow it when your patients aren't dead? Is this how you medicate using narcotics? RSI meds? What do you believe to be the purpose of these protocols, if not to be followed in these situations (other than a reminder of the incorrect beliefs of yesteryear)?
