The problem with that would be that what it's right may differ from person to person. For some, killing a person who is balancing between life and death, suffering an endless pain, will seem as the right thing to do. For others, the right thing would be to do everything they can to keep that person alive as long as possible even if it only serves to prolong the pain and wait.

I fight for Athena's justice, but if hers is true justice or not is something I can't judge. I can just believe in it and do my job, I don't care about anything else.
