Morality for me is doing what is best for someone. What is 'best' depends on your situation. If you are sure that you are helping your friend out then it is a moral act even if it turns out to be an incompetant act. I also think that there are moral standards for yourself, masochism is not ethical.
Respecting autonomy is one aspect of doing what's best for another person but there are exceptions when respecting another's autonomy is unethical. If someone is suicidal and wants you to go away then it is not an ethical thing to leave. However leaving someone to kill themselves is not what is best for them (if you don't agree on suicide being unethical then I will elaborate) so it is ethical to use physical force to stop them killing themselves (calling paramedics to put them in an asylum for a night is an option.)
A real life situation for you: I went to a bikram yoga studio yesterday. It's very intensive postures done in a hot sauna, great fun but very exhausting. We were told not to leave during the session but rather to lie down in the sauna if we got too hot. One guy decided that he couldn't take the heat and so stood up to go. The instructor told him he couldn't leave. He walked past her and left. She did not make any physical motions to block him, only verbal. In your opinion at what point do verbal actions count as unethical? (side note: I was very surprised to hear we weren't allowed to leave. I've been to bikram yoga before and there was never any question that you could step out if you needed to.)
