Just saw a wounded drunk guy

Hi, so while going to the gym i saw a drunk guy laying on the street. at first I was about to ignore but than I saw his face was covered in blood. I asked him whether he was okay and he asked to call a taxi. I replied him that I dont know enough japanese for that but went in to the gym to ask help from someone. the other person just took one look at that guy and said that person is just drunk and even if he is wounded he needs to take responsibility for his own actions. eventhough I understand where he comes from ( also he was very nice talking to me ) but was it still right to leave that person lying there ? I feel a bit lost and also need advice on how to navigate such situations in the future. Thank you for your help.
