If I was given total control over your life and made you work for me, would you be ok with that so long as, according to me, I treated you well enough? I doubt it.
That isn’t the point though. This is not a debate about whether anyone thinks the rat is being treated well.
The rat did not consent to this (because it can’t), so this is, factually, forced labor. I am ok with it in this situation, but let’s call it what it is and express gratitude for what the rat did to clean up human messes.
Second, you can’t do something heroically if you either 1) don’t know what you are doing and what the risks are or 2) there are no risks. Take your pick, but either way it isn’t heroic. The rat did a great thing for us but hero is not the right word.
