I'd say the same thing slightly differently. If you're willing to go risk your life treating a level-4, usually fatal disease, the minor inconvenience of a quarantine on return shouldn't stop you--in fact, if you really care about people, you'd want to make sure you weren't bringing the disease back. This nurse that's going to sue is both a convenient political tool and a narcissistic do-gooder, the worst kind.
Less blunt than how I said it. Thank you.
