The first thing is that there are no universal sets of morals. Ethics is a totally different beast but it’s something I’m not sure a young kid can wrap their heads around. But following “the rules” is something you can teach a kid and works until they are old enough to know when to break the rules.

One thing we stressed to our son is: if you break the rules/laws, you will eventually get caught. So make sure whatever you are doing is worth the consequences.

There’s no need for some magical god to punish people, just the fact that, eventually, someone will figure out what you did (or more likely, they’ll tell on themselves). It’s worked so far…
