It’s more like “trick or treat” vs “candy or we egg this joint”.

The one is social accepted, polite, and doesn’t overtly state an intention to harm but it does imply it. The other is exactly the same, but it’s direct, no implication, just one or the other.

Another example would be “you gotta pay us for protection, you wouldn’t want anything to happen while you’re here.” Vs. " Pay up or we cut you".
