I'm going to make money from a tragedy
How are you going to make money from a tragedy?
I'm going to start selling injury cases to lawyers.
I see what you mean by tragedy. You are being helpful by connecting victims with lawyers. I don't think there is any issue with profiting from that.
Oh no, now I have a guilty conscience. Why does life have to be this way?
I don't think you need to feel guilty about your job. People who have been involved in injuries need good lawyers to represent them, so you are helping them out by finding the right people to work with to resolve their cases.
