Why be good?

Hardly.  I would admire him for telling me before I left him with that child.

I think you're mistaken, no one said anything about him telling you, you just "know" this particular man has these thoughts, it's a hypothetical scenario.

Here's a question for you Huggy,

Is is it condemnation of a man with small pox to prohibit him from entering a nursery full of unvacinated children?

Yes, by definition. When people are placed under quarantine, that's exactly what it is.
