You are taking your dog for a walk a long the banks of a river
When you notice someone drowning. The person you realise is a local thug and lowlife who you have had run-ins with in the past.
With all the commotion your dog jumps into the water and also begins to drownd.
You know that you will be able to save one of them before the current pulls the other under to their doom.
Who do you save?
