Except this is science, not daily life. There is a process and procedure expected to ensure integrity of results and consistency in the process. Yes the ethical guidelines are there to attempt to achieve some morality, but from a scientific process perspective it doesn’t matter if you agree or disagree or have a different morality. It’s a process integrity question above all else. You aren’t prevented from doing science however you feel is moral, but if you don’t conform to the process requirements front to back, don’t expect journals to publish your work. It’s like I tell engineers - you can prefer tabs or spaces or place braces wherever you want on your own time, but when working in a shared code base, show your creativity in your ideas not your coding style. Likewise show your moral beliefs in your life, but when doing biomedical research, follow the ethics rules because they’re part of the shared process.
