Wheather you want to get home or not its your decisions its the safety of the passengers which is more important. Dont know the extent of the injuries if it was only cuts and bruises fair enough. If it was a serious cut/bruise would the cabin crew be able to perform his/her SAFETY duties i.e. assist with a fire, evacuation, deompression etc etc. Dosent matter if you cant do the drinks/food service thats not important as your main reason you are there is for passenger safety.
