a man's got to do what a man's got to do

A man must do what he feels needs to be done, even if it is dangerous or undesirable. Sometimes said ironically. It might be dangerous delivering water to the refugees, but a man's got to do what a man's got to do. I know it's a lot of cotton candy to eat, but a man's got to do what a man's got to do.
