No, the advice in The Prince is directed at the fact that at political scales morals need to be reexamined. For example: just the way our immune system would give up the antibodies in order to get rid of bacteria.

For example - we say “Platonic love” - but we rarely mean it in the same way Plato meant it, where he was speaking of divinity; rather than just the absence of sex.
